First of all: Carles is a really good host. I had to text him many times on our arrival date because of the delay of our flight, and he answered directly so we could change the "Check in" several times. Highly recommanable!!!
The flat is a beautiful place, lovely furnished and has anything you need (soap, toiletpaper,iron and and and). Another big plus is the aircondition.
For everybody who wants to visit Valencia, it is a really good choice to pick Carles place. It couldnot be netter located.
