The apartment had a really nice location and Paul is really friendly. Although he speaks almost no english he really tried his best to communicate. The apartment is really tiny, dark and the neighbours are really loud in the morning and in the evening. It's difficult to cook in the kitchen because there's only one stovetop and little cooking utensils. There was a really bad smell coming from the bathroom sink throughout the day.
Generally speaking the flat is alright if you want to stay for a few days in Valencia and are out and about most of the time anyways.
