coming from an IT install field I facepalm at some of the suggestions. yeah wireless is simpler, but if your dad is cool with it and the walls are just like a simple drywal, go to your local hardware store and buy a drywall saw, and get 2 LV1 pieces,and some simple wall plates that will screw onto the LV1's that will allow an ethernet cable through. no cable through the hallway problem solved. the only thing you need to be concerned about is not hitting the electrical wires in the wall, but that is easily taken care of by not cutting in the same stud gap that the power is in.
Please note, since you mention your father, it would be best to get his permission before cutting holes in the wall.
You will want to mark out the wall carefully using the lv1 so you don't make the hole too big. run the necessary length of a cat5 cable through, then put the cable through the wall plate and connect the wall plate to the lv1 that is affixed to the wall. Now you have your cat5 and no ugly hole in the wall. make sure to do this on both sides of the wall of course.
One last thing, if your house is ancient (like built in the early 1900's or the late 1800's) this solution may be far harder due to the construction style of the day and age.
for those that don't know what an LV1 is, http://www.amazon.com/Arlington-LV1-1CS-Voltage-Mounting-Bracket/dp/B000UEAJWU They are basically wall openings to allow low voltage signal wires through the walls. This is used to keep cabling to networks, video, and more hidden from view and gives a nicer cleaner look to many comercial installs. for home use, it makes getting cables from one room to another far easier.
You can buy one and mix them up however you want. If you are going to be making new holes in the wall for these jacks, keep in mind that you will also need something like below before you can use these plates:
Nothing wrong with that plan. You could just cut LV1s in and install key stone jacks that you plug the cat patch cables into.
They will be cheaper at a hardware store as they would not be trying to cover the shipping fees.

I see you solved your issue with a powerline. That's good. If you ever want to run wire in the future though, or if anyone else reading this does, see the following. As an IT pro, the "proper" answer is this:
Is this a "normal" US house? Is there attic above you? Is there fire block installed in your wall? You can tell this by using a stud meter and testing BETWEEN the studs, horizontally. If there is no fire block and attic above, you cut a hole in the wall with a dry wall saw, sawsall, etc. (the size of the bracket linked below). You go up in the attic, drill a small hole in the 2x4 top plate directly above the hole.
Go to lowes, get a low voltage bracket. (like this:https://www.amazon.com/Arlington-LV1-1CS-Voltage-Mounting-Bracket/dp/B000UEAJWU/ref=sr_1_7?dchild=1&keywords=low+voltage+bracket&qid=1621489922&sr=8-7)
​
You feed your cable, that you can also buy from lowes, home depot, etc. up that hole into the attic (or perhaps down the hole since that will be easier without a fish rod). Then you go to the wall you want the cable to come out of, above it in the attic. Repeat the same process to get the wire into that second hole, use another low voltage bracket.
Get two of these faceplates, one for each hole: (https://www.amazon.com/gp/product/B074HGD1R3/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&th=1)
Get two of these RJ45 keystones: https://www.amazon.com/gp/product/B004D5PFGW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
​
Punch them down with this tool according to the B color scheme you will see on the side of the block: https://www.amazon.com/dp/B0072K1QHM/ref=emc_b_5_t
​
Congratulations, if you did this right, you now have an ethernet connection from room to room. Now simply plug each device into your new jacks and you will have connectivity.
​
If you have fireblocking, it will be more difficult, you can either cut away more drywall to drill through the block, or you can use a long flexbit to drill the fireblock from the attic, like this one:

​
It will be a pretty involved, moderately difficult process for a first timer but a breeze for any installer. The cost of this would be:
Total: Roughly $20 or so for consumables for anyone who has all the tools, you could spend $500 on all the tools if you want to buy them all like a fish tape, 1000' cable, sawsall, magpull, screwdriver, RJ45 termination pod, label maker, toner/test kit, etc. etc. etc.
As you can see it's not very economical to buy that stuff if you only plan on doing it once. The average ethernet drop price, according to google is around $150-200. For a really small job like that, I might even say $250? I guess it depends on what market you're in, etc. I have a $250 minimum (it's just not worth it to me to 1. drive to customers house 2. get info on job, specs, etc. 3. go write up a quote, email it, follow up with customer 3. schedule an install apt 4. install 5. follow up for payment for, say, a 100 job.) Not saying you couldn't get a neighbor to do it for $20, provided he has all the tools and is friendly and helpful. For a friend, I would do it for free and it would only cost me $20 or so in consumables (I have thousands of feet of cable and faceplates/jacks by the hundred on hand, plus all the tools so it's just some time for me).
​
The cabling vendor I used to use when I worked at another company charged around $200 a drop even for easy huge bulk jobs (which I typically charge 100 or so, say 5+, maybe even less depending on difficulty/number of drops in the same location, etc.). For example a building floor rewire (roughly 2xx ish drops) was almost $50,000 for Cat6 (I don't *think* it was even plenum). I want to say maybe 225ish around 46k or something like that. So pretty close to 200 a drop and that was standard office drop ceiling (very easy stuff).
​
So long story short, you may be able to get someone to show up and do it for a hundred bucks, and at that price, it would be very worth it (assuming the work is good). I would not be surprised if they quoted you 200-300 bucks though. I wouldn't pay anything above that and remember that a one drop job is not going to be economical so it's going to be "over priced" just because of the call out fee. If you wanted, say 10-20 drops, I would probably only pay $100 or so each.
Any questions or comments, let me know. Thanks.
Looks great... make it perfect:

Is this what I want to put into the hole in the wall to attach the wall plate to?

If you like cleaner looks you can use these low voltage single gang boxes. I used them to run cat 6 between my entertainment center and my home office.
