We stayed here with 3 teens, and it was clean, aery, very comfortable, and equipped everything we needed. The apartment is in a nice and calm neighborhood, a little more walk needed to the attractions, or the metro is 7 min walk.
We liked to stay here, the staff were kind and seemed helpful, although they couldn’t help us so much when i needed local services or suggestions.
So the apartment was really ok, but I missed the feeling that i feel, when I book from a “really” local host. It’s a very good choice, if you only need a nice place to stay in lovely Barcelona.
