The apartment is centrally located and easy to access from the metro station that serves trains coming from the airport. The apartment itself is spacious and fully equipped to make the stay pleasant. Facilities in the apartment is superb.
However, one negative point of the apartment is the noise level at night. You could hear people having loud conversations downstairs and the noise from cars and especially motorbikes will keep you at night. What surprises us the most was the noise from building works being done till late in the evening and early in the morning. Only way to solve this issue is to close the windows. However, the room gets stuffy when this is done.
Nonetheless, after a long day out exploring Barcelona, you'll be too tired and you will sleep through it.
