We had a nice stay at this place. Communication with Claudio was excellent. He was friendly and helpful and gave us a very warm welcome. The appartment was very clean and in fair condition. The location is extraordinary, close to the city center and a 3 minute walk from the central market. It's also mostly quiet at night.
The only issue we encountered was that the rooms are not separated by doors, instead the space is open except for the bathroom. The bathroom/toilet is separated by a sliding door and directly next to the bedroom. This layout was rather inconvenient to us as light sleepers, since there is no way to get up or use the bathroom without waking the other person. Everything else, save for the slightly smelly A/C, was great. We can recommend this place to anyone looking for a good value, central appartment in Valencia.
