We had a great stay at this lovely apartment. We traveled to Barcelona with our 2 teenage daughters and we had plenty of room.
The location is great. The metro, grocery, bakery and restaurant are steps away. We enjoyed eating at the restaurant on the ground floor on our building.
One tip is to call the elevator when you first arrive. We climbed the stairs to what we thought was level 3 (knowing ground floor is usually floor 0) but in this building you are actually going to the 5th floor (US 5th floor). So just get in the elevator and push the button for floor 3 and you will end up in the correct place. You’ll know you have the correct unit because there will be a Stay Unique sign on the door.
