I stayed one week at Julia's house with some friends and we all found it really nice and confortable. It takes just 10 minutes to the metro and the neighborhood is calm and you can find several supermarkets. You can even reach the Sagrada Familia by foot in about 15 minutes. The only problem was that the dishwasher didn't work properly and although I texted Julia to make it fix, nothing has been done. Apart from this I really enjoyed my stay.
