The hotel is clean and comfortable, and well located in the north of the city only three metro stops from the centre. It is close to Park Guell as the name suggests, but be warned you need to have booked tickets online for the park or you can't get in, and they sell out very quickly.
The biggest negative issue with the hotel was the lack of any soundproofing, you could hear the neighbouring rooms far too easily, and that's before I talk about the bathroom.
The bathroom was clean and everything worked, but the door was glass, which gave no privacy in terms of sound which really is not pleasant.
There was also not tea/coffee making facilities in the room which is highly unusual in my experience.
The swimming pool on the roof gives great views, but is extremely small.
