Maria maintains a lovely apartment, which was perfect for our family. It was great to have a separate room for our toddler. There were ample towels and bedding, and everything was very clean. There is also a fully stocked kitchen (including spices, tea, coffee, pots, pans, etc.).
There are AC units in the living room and the main bedroom, and although there was a fan in the smaller bedroom, we did find it got hot in there if we closed the door (note we were there late August).
The apartment is centrally located, right off Plaza Catalunya, meaning you are steps away from metro, trains, shopping (Corte Ingles - large department store/super market, and Passeig de Gracia - fancy shopping strip), and sights (Gaudi's Casa Mila, for example). The area is seedy, but Maria informs you of this, and through signs before leaving warning of pickpockets.
Maria was also very accommodating when our trains were delayed, meaning we didn't get in until 10:30pm. She made sure someone greeted us with a smile, a helping hand, and a warm welcome.
Overall our experience with this Airbnb was lovely! Thanks Maria!
