Me and a group of 7 friends stayed at Beatriz's apartment for 5 days and all was perfect. The apartment is very big and more than enough to host 7 adults. The living room and the courtyard are just amazing and great to chill-out!
The apartment is not very close to Barcelona's town centre (around 20 mins by metro), but the neighbourhood where the apartment is (St. Gervasi) is great - full of small shops and good restaurants!
