We've stayed for three nights at Anna's place, we are a family of five, the kid are 5, 6 and 13. The apartment is well located in a quiet neighbourhood, we could park our car in the street, right in front of the house, without any charging.
The metro station is only a five minute walk, the perfect way to get into the city.
The apartment is really big and well equipped and nicely decorated.
Anna is very friendly and helpful. She lives in the appartemnt downstairs with her family. Her english is perfect, loved it! She has sent us an email with all kinds of information, from routes to supermarkets, opening times for the nearest bakery to ground plans from the surrounding. All this information (and more) was also inside the appartment, very convenient! Although Barcelona suffered from a heatwave, the apartment kept really cool since it had AC and automatic blinds for all the windows.
We really liked the place and definitely recommend it!
