The stay at Gabriela's​ studio was great. The apartment was quiet, clean and Gabriela answered quickly when I had any questions or extra wishes. I stayed​ 2 months, the only thing you might consider is that there is no washing machine in the apartment (however a laundry is in walking distance), but anything else you need is there.
The apartment is also suitable for 2 persons (3 if one sleeps on the couch). I'd definitely stay there again if I needed a flat for a couple of weeks in Barcelona. Thank you Gabriela!
