First, the location is really perfect at Marina Metro. You have everything around you: supermarkets, restaurants, cafes, a Tram station, Metro station, several bus stations. You can get to beach in 15 min. You can reach any important places in Barcelona within 30-40 min.
The flat is very quiet at night because is in the back-building, althoug the whole building is in front of a big street. We got everything needed to feel comfortable. The terace is very cool, where cool wind from the beach blows in.
Communication with the agents went super smooth.
All-in-all we had a very nice stay at Barcelona.
