We really enjoyed Simone and Georgina's apartment! It was very spacious and comfortable and just like the pictures. We were a group of 7 people and found it very comfortable having two bathrooms, a useful kitchen and a nice balcony. It only has beds for 6 people so our 7th friend had to sleep on the sofa bed, which was surprisingly comfortable.
The location is in a very nice neighborhood with lots of nice restaurants, bakeries and supermarkets which was very useful. It isn't as close to the metro stations as we thought (10 mins to the closest one), but the area feels safe to walk even late at night and there's lots of bus stations 2-3 mins from the apartment. It is also 15 minutes from Plaza Catalunya so when we weren't tired from the long day we just walked through the sweet neighborhood.
Not that it matters but the apartment seems to be rented by some company. It can be useful for some that want more services (more like an hotel) but less suitable for people that look for an authentic stay in someone's apartment. Anyway a very nice girl called Alex brought us the keys and showed us around when we came and was very welcoming.
Overall we really enjoyed our stay in this apartment and recommend it.
