These are the kind of hosts you hope to find on airbnb. I got lost trying to find the place and Guiermo (sp) actually came and got me in his car....really how nice is that.
This is a very stylish little flat, and the location is right where you want to be. I absolutely loved it. Of note it can stay loud at night until midnight and beyond, but that is only because everyone here doesn't really go out to dinner until 9 or 10. I did fine with earplugs. The mattress is super cozy, and is completely fitted out and cozy.
I enjoyed it so much I am coming back after a weekend in Denia for another few days. I highly recommend. The only note I would make is that it a charming but small place, especially in the bedroom and bath. So if it was two people of larger proportions, it might be a tight fit. You can use your judgement on that one.
All in all you won't find nicer hosts, or a better value in all of Valencia.
