Listing and pictures are accurate.
Place is very nice and the location can't be beat.
We were there during the festival of Sant Dionis, and so it was fairly loud late, but I think that was true for most of Valencia.
The apartment is situated right on a town square with a couple of restaurants, so if the most important thing for you is quiet, this may not be the place for you. But if you want to be right in the old city, walking to everything you could want to see the apartment is perfect.
Bathroom is newly renovated and shower etc. are first rate.
If we're back in Valencia I'll look for Carlos's place again.
