Great place to stay. When I checked in, I thought he place would be noise because it faces the street. However, the place was quite peaceful, very sunny with the sunlight in the bedroom and a very clear kitchen. All the appliances and utensils you need to feel at home. Very good internet speed. Nearby supermarkets and the subway just by the corner, although it's worth walking around.
It is well located, about a 10-minute walk from the Sants Station where you can basically go anywhere. I recommend you visiting the Monastery of Montserrat, amazing experience and the train lives from this station.
