I had a perfect stay at Pilar's place, I stayed there for 6 nights.
The Apartment is perfectly located at the heart of Valencia, in the middle of the most pleasant parts of Valencia El Carmen (old town) and Ruzafa (urban&cool district with so many Bars and Restaurants).
As Metro station is so close (Xativa) you can also reach other parts quickly - as the Airport or the beach.
The Apartment is exactly as described, and having your own terrace is a real bonus!
Pilar was very friendly and helpful when help was needed.
I can totally recommend her Appartment!
