Mary is a very nice and kind person. I haven't met her personally, but we had much contact via internet. She is very willing to help you with all kind of things. She has informed us much about the location and the details of the stay, before we came to Barcelona. Because our flight to Barcelona was so early in the morning, she agreed with an early check-in which made things much easier for us. The apartment is beautiful: it's perfect for 4 people. Very clean and cosy. Nice kitchen and bathroom. It sometimes was a little bit noisy (but I guess this was the loud television from the neighbours). The neighbourhood is quiet and peaceful. Metro is about a 5-10 minute-walk which is fine. I would definitely stay in this place the next time.
