A fabulous apartment - I cannot recommend it highly enough. Clean, comfortable, spacious and well-equipped! Andrey and Sasha were a pleasure to deal with, and responded very promptly to my queries.
Perhaps the apartment's main strength is its location - 5 minutes walk to the incredible central food markets, 5 minutes walk to the riverbed park if you fancy a nice jog and 15 minutes walk to the train station. The apartment is also relatively quiet, despite being in an otherwise lively area of town.
Had a great week and a half stay, and will definitely be coming back when I'm next in Valencia.
