The room at Juan's apartment is a perfect place to visit Barcelona. There is a Metro station is 6 minutes’ walk from the apartment and there are many bus stops all around so it's easy to move around the city to see it's all attractions. Lidl is 10 meters from the building entrance and there are many restaurants and bars in the neighborhood. If you like a good beer I recommend visiting Brewdog that’s 70 meters from the apartment ;)
The room itself is clean and has everything I needed for the stay.
Juan Carlos is a very kind person so I guess I'll have to learn Spanish till my next visit so I could get to know him better ;)
