The flat was sparkling clean when we arrived and the check-in with Nina was very easy and friendly, she was waiting for us at the flat and gave us a lot of tips about where to eat in the neighborhood etc . She also arranged beforehand for our pickup by a taxi at the airport, which was really appreciated. When I contacted her for a question during our stay, she was very responsive and helpful.
The flat is nicely decorated, the bathrooms are really neat. There is everything you need but it is a flat made for renting so it feels a little bit standard and impersonal, like a flat in a hotel. We were a bit disappointed because the living room and kids bedrooms (not the main bedroom which is really big) are much smaller than they seem in the pictures. We were 4 (2 adults and 2 teenagers) and the flat size was fine, but I guess that it would be quite tight for 6 people. We liked the location, as it is literally minutes away from the Sagrada Familia by foot and in a residential area of large avenues. The windows isolation is very good so the flat was really quiet at night. This flat is a "safe" choice, with no issues, for people interested to stay in this area.
