Jumpers and jackets at night right [now](https://weather.com/weather/tenday/l/Valencia+Valencia+Province+Spain?canonicalCityId=c79a68f894bf3a29f287864cc8b9d1d7b0a7c80b006aa57734b1f950571ebeed)
Amazon (Spain) seems to have it
Para moverte en ciudad la mejor app por lejos (para mi, eh) es Geovelo. Tienen siempre bastante actualizados los datos y al momento de pedir direcciones podés elegir si querés un trayecto mas directo o más seguro (aprovechando a máximo los carriles bici)
There are all-inclusive tourist cards with unlimited bus/metro, and also you get some free entry to museums etc. Available in 24, 48 or 72 hours validity. Not sure on the price though. You'd need one card each, you can't share one.
For the SUMA 10, yes, you can share it, just tap it, let your partner through, then tap again and walk through. On trams, just tap on the platform scanner before boarding (tap twice for 2 people). Don't tap when you get off. On buses, tap when you get on (twice if 2 people), and not when you get off.
SUMA trips have one free transfer metro-bus. You have to board the bus no more than 60 mins after your metro journey started. Mayb longer for Zone B, I'm not sure. Anyway, it's unlikely you go over this time.
Here's the Suma app, you can check balance and also recharge the card in blocks of ten trips (pay by card). Your phone must have NFC for it to work. https://play.google.com/store/apps/details?id=com.transermobile.recargasuma
You can also check your balance/recharge at any ticket machine (tram or metro). Some tram ones are cash only, some card only. I think all the Metro ones are both. I find it easiest to top up with the app personally.
>Yes please
I'm no sure about their quality or if they are available in English though
Tourist guide: http://wikitravel.org/en/Valencia (I have no idea if there is a book better than other in this area)
Historical: Historia de la ciudad y Reino de Valencia by Vicente Boix
Novels: La barraca; Entre naranjos by Vicente Blasco Ibáñez
Graphic novel: VALENTIA (edited by Norma editorial)
Idk how complete is each one (or if they're available in english), but there's several Apps for that.
Love Valencia and the official Fallas 2020 App for example
