Beautiful apartment, close to the sea, close to the metro. A/C working very well. I’ve spent there a week with 7 friends and everything was perfect.
The only little negative thing is that you are in the gipsy part of Valencia, people are not dangerous, but buildings around are dilapidated (not the one you will stay in, to be clear) and some of them is a bit dirty with rubbish on the street.
I strongly recommend to spend your holiday there, awesome quality/price. Awesome host.
