We had a great stay for two weeks with two small children.
Javier was an excellent host, generous and fast in response to our questions.
The flat was very nice and clean with a big terrace which is perfect for children to play at.
The flat is on the first floor and has a quite narrow stairway and no elevator, soo with a baby stroller it's a little tricky to get it inside.
We are very satisfied with both our host, the flat and Valencia!
