My three friends and I stayed here for a week and we were all happy with the apartment. The place has a great location, we were able to walk almost everywhere but also took the metro from the Universitat station when we were going further. The metro is about a five minute walk from the apartment.
The place was very comfortable and even bigger than I thought it would be, and just as clean as the pictures show. The AC worked well and it was nice to be able to sit outside on the terrace for meals. The kitchen had a large fridge and freezer, a little dishwasher and even a washing machine, everything you need! Also the beds were comfortable and there were fans in the bedrooms if you'd need some extra cool air during the night. The Wifi worked pretty well too!

The only negative thing was the thin walls which let in noise from the other people in the building, but it didn't bother us much. However if you are sensitive to noise when sleeping it's a good idea to bring earplugs!
