This is a great appartment! The location is excellent, I don't think it gets any better. It was spacious and clean. It looks even better than on the photos. There's everything you need: towels, shampoo, showergel and a hair dryer. Carlos also gave us some tips for restaurants. He is very nice and you can always contact him if you need to.
The only problem is that it's a bit noisy. You hear the drainage from the neighbours and the neighbours talking/yelling. The church bells ring every 15 minutes, and you hear them quite clearly. However, sleeping with earplugs in solves this problem. We were prepared so we slept well anyway. The bed itself is very nice. Also, Valencia is amazing!
