We stayed in this apartment for a month and it worked out perfectly for us!
The location is excellent, on a quiet street. Which, if you've been to Spain before, you may know it's not easy to find quiet accommodations. This apartment was absolutely quiet which we really appreciated. Plenty of space in the apartment and it has everything that you need for either a short or long stay.
The communication with Adela and her friend who checks you in/out of the apartment was easy, quick and they were very fast to take care of any problems or needs that we had.
I highly recommend this apartment for your stay in Valencia!
