The stay was pretty lovely, we felt very welcomed! Flat has all necessary facilities.
Very close to the metro station Alfons X, but also walkable towards city center. Take advantage - Sagrada Familia is just 10 - max 15 min walking down by one street or hop on the bicycle and you gonna be right there in 5 min.
Nearby enough small markets, bakeries, and restaurants!
Alexey is very attentive to details, apartment was always clean, he is very helpful and flexible - we enjoyed the stay!
Well recommend to spend your time in beautiful Barcelona!
