We are a family of four (parents and two small kids) and we enjoyed staying in this apartment. The location is perfect. We came during the heat wave in Barcelona which lasted our first four days. As the appartement does not have air conditioner, it was a bit hard during these hard couple of days. But it must be said - the apartment is actually very well ventilated, the only hard spot is the little bedroom which does not get air circulation. But Josep bought a small fan for this purpose, and it made all the difference. Once the heat wave passed, we never once thought of air conditioner, as the flat is very well ventilated.
The communication with the hosts was easy. We got some nice restaurant tips. We have no problem recommending the place.
