We had a problem with the bathroom. The host was very responsive and sent a plumber in a matter of few hours. Some bad smell persisted through that day.
The host actually refunded some money for the inconvenience, even though it was clearly an isolated incident and definitely not his fault.
Also, the TV is basically useless as the signal is poor and scrambled. But then again, it is a waste of time to watch tv while staying in Valencia so not much trouble for this.
The place is very spacious and nice, it has everything you need. Even a dish washer machine which was great for us.
Do take some house slippers with you, we didn’t and its all tiles on the floor sometimes it feels kind of chill in February.
All in all, the place is nice, the host is an excellent one and it’s a good place to stay, at a reasonable price, when you come to Valencia.
