Nice apartment (and nicely decorated), clean, with everything you need. Very well located, close to the subway and buses, nice restaurants in the area, walking distance to the Sagrada Familia, Arc of Triomf...
I might have missed in the description that there is no elevator, the apartment is on the 4th floor and it can be quite exhausting after a long day of visits ;)
Alvaro has been very easy to communicate with and reacted very promptly when we had a concern. Easy check-in and check-out !
