The flat is very nice and clean, it is as shown in pictures and there is everything you need for a nice stay. We found it perfect for a 4 people family.
We also had a cot for our little boy and as we placed in the little studio we can say that everyone had their own room :) (If you ask for the cot, bring sheets)
We really enjoyed the cool terrace during the hot evenings in Barcelona.
We managed to park our car very close to the apartment, for free.
Javier is a very nice host, we arrived earlier than expected but that was no problem. The area is very well served, there are cafes, supermarkets, shoeshops and basically everything you may need, within a stone's throw.
I would really recommend it.
