We were a group of 5 and enjoyed our stay.
The apartment is very clean, modern and you feel comfortable.
The location is pleasant, close by you have the possibility to buy groceries, or go to restaurants. With the metro and the train nearby, exploring Barcelona is very easy.
We appreciated the communication with Wally and his recommendations, which he gave us at the beginning. On the second day we asked for an additional blanket and on the same day he brought us one. Very nice!
