We were travelling with the group of eight peaople in Barcelona during mid summer and stayed five nights in Pink House.
The apartment was just like in the pictures. There was a lot of space and the rooms were seperately, when travelling with the group you still can have your own space and privacy if you want. We were having a barbeque one night and it was awesome! The kitchen is fully equipped and the terrace and pool area is perfect for dining and hanging around with friends.
The location is not in the city center but you can easily take a bus to Plaza España or Plaza Catalanya, the bus stop is just one block away.
The host was really friendly and waited us at the apartment even though we were nearly one hour late from the appointment. The communication was easy and quick.
We can highly recommend the Pink House for same kind of groups than us.
