In August I was in Valencia with 7 friends. The first day there were a few small problems, but that was immediately resolved that same day.
The apartment is beautiful and spacious enough for 8 adults. It is also in a prime location with many nice restaurants in the neighborhood. The supermarket (Consum) is 100 meters away from the apartment. Elena is a very nice hostess and everything is well taken care of. I would definitely go back there!
