Check in and out very easy and smooth. Monica's friend was waiting for us in front of the apartment with the key.
The rooms are not very spacious but enough beds for us all (5). We didn't have to use the sofa bed.
I selected 4 stars because the shower pressure was weak, and it was not easy to stabilize the temperature. The bed rooms have windows, but one facing the street is too noisy, the other windows were facing the inside of the building, so no air circulation..but of course the room has one AC so during the night we opened all the doors and used the AC. Everything worked very well and we felt very at home, and relaxed in the room.
The location is very convenient, many 24h open convenient stores near by, nice bakeries and organic supermarkets, good restaurants, Sagrada Famillia walking distance. I recommend this apartment for a family and friends who wants to explore the city, at the same time relax and rest well with your family. Probably because it's located in front of the big street, the apartment is not so quiet . The sound of the cars is always there.
