This apartment is at a great central location! It is right next to the downtown center of Plaza Catalunya with lots of shopping and food, and walking distance to many Gaudi attractions (Casa Batlló, Sagrada Familia).
The house is a bit smaller than was expected from the pictures! The bedroom with two beds has very little space between the beds, not even enough to fit one person to walk through comfortably. The upstairs bedroom also had a VERY low ceiling. If you have taller members of your traveling party, you should probably find a different location. It was pretty uncomfortable to shower upstairs as well for the same reason. There was also construction going on in the apartment building very early in the morning, which was not mentioned before we arrived. Also make sure to have the host explain to you the air conditioning and washer/dryer, since their operation is not intuitive.
