My family (4 person) stayed in this apartment for five days during mild winter in Barcelona.
The apartment is very comfortable for us (plenty of space for all of us), and it has a complete amenities for my family to take care of our stuff (washer AND dryer, complete kitchen utensils to cook for breakfast, Wifi) while we enjoy Barcelona. As for the location, it is basically a perfect location for our stay: 3min walk to 2 Metro stations (from there to access every locations in Barcelona), 15min walk to Sagrada, abundant mini-market around to get your needs, safe (walking back from Metro at midnight after watching the game in Camp Nou), and quiet location (apartment facing the quiet street).
Lobsang, our host, is very attentive and ready to help us. On our last day in Barcelona, she helped us to arrange a taxi booking to airport since our flight leaves very early in the morning, and called me to make sure I receive her message about the taxi booking.
I would definitely recommend this place to anyone who wanted to visit Barcelona.
