The apartment is situated in a very nice district, 15 min. walk from Park Guell and 25 min. walk from Sagrada Familia and Casa Vicens. Bus stop is 1min walk. Metro is 12 min. walk. You have few shops around. So you are sorted for a nice stay.
The apartment is not very big but comfortable for two adults and two kids. The kitchen and bathroom are well equipped. Living room has TV and air conditioning. Everyting is clean. Keep in mind that you are in the middle of a city so streets can be noisy. We slept with no problems, having windows closed and air conditioning turned on (hot summer 2022).
I would recommend the apartment for everybody who want to have a nice stay in the centre of Barcelona.
