The place is in a great location! Near to the city center, subway, montjuic and barceloneta.
Our staying was during the end of August and it was super hot (33 C). The apartment has no air conditioning and we had to sleep with the windows open all the time. The street was super noisy, even during the night so it was a little bit hard to sleep. The second room with sliding doors for the leaving room was really small and impossible to sleep with the door closed.
Also, the bathroom is really good but the toilet is separate and really small.
