I had a really great time here. Iván & Carmina are lovely people, always helpful and nice. They helped me a lot.
The studio is amazing: clean, functional, well equipped and full of light with 3 windows (one with a small balcony provided with table and 2 chairs). And the terrace on the top is really the top.
The location is perfect, in the very old town center, but even close to the park... Walking around you can visit the main attraction and find good bars and restaurants (the hosts will suggest you something).
If I had to go back to Valencia I would definitely stay at Iván & Carmina again.
