Hi, Gaby! I use Simyo all across EU actually, it's one of the best deals in Europe :) For more information, please see this wiki prepaid-data-sim-card.fandom.com/wiki/Spain -- it's the best resource on prepaid data sims anywhere in the world. The only catch is if you're a resident you can get much better deals using contract subscription.

Use the pages Idealista and Fotocasa, the spanish used them!

thanks for your replies! Housesitting is not really an option unfortunately - I prefer to rent a flat for a few weeks/months.

Ruzafa seems like a nice neighborhood. I am also asking for airbnb alternatives because airbnb prices for full apartments are quite high. I am a bit surprised but maybe that’s normal rental prices in Valencia and I am just very late. Or authorities started targeting airbnb, so that there are increased costs for landlords and less competition.

Aw! Valencia was my first nomad home! I got my accommodation with Airbnb so can’t help with alternatives. But I lived in the Rusafa area and can highly recommend this. It’s an arty neighbourhood with a few nice cafes to work in and a short walk into the centre.

If you don’t mind some responsibility you could give housesitting a chance. There are many offers in Spain and if you are lucky you could get quite a big house with all amenities. Most sits also come with pets, however. I’d say TrustedHousesitters.com and MindMyHouse.com are the best sites. If you don’t want to spend much money, try MindMyHouse first, it’s only about 20$.

Edit: If you sign up, I’d love to give you my referral link.
