We were on holiday in Valencia and spent 5 nights at the apartment. The location is the best part, we had everything at walking distance. The check-in process with Barbara was smooth and communication with various people previous to check-in was also quick and without issues.
The apartment is spacious for 2 people and we found most of the apartment clean, except for a bit of dust in some of the areas.
The biggest issue we had is that the building is accessed by a corridor shared with shops and a night club (!!). The only window of the apartment faces this corridor, which has its pros and cons.
Pros: as there is no direct sunlight, the apartment is cooler than outside.
Cons: lack of natural light and fresh air. Very noisy during weekends when people are leaving the night-club.
If you're staying during the week, it should be fine. But bring earplugs if you're planning on spending the weekend here.
