The overall experience was very very good. We had to change our arrival time several times and the host was very understanding and communication went well.
Flat is huge with a cool chill out living room. It has everything from AC to internet, crockery, towels and other stuff.
Thr host was very nice and helpful and provided us with loads of good advice.
Parking can be found relatively easy on the streets around and the location is very good to visit the city centre but not close to the beach (can't be both).
Only downside is that sometimes there is bad sewage smell that comes from the bathroom but noticed this is an issue across Valencia.

Highly recommended!
