It’s really close to a Metro station and the central plazas (Plaze de España); and is at the base of the Montjuic mountain/park, which you can walk up to get a nice overview of the city.
Everything is super tidy and clean inside. There’s also a cute little balcony that overlooks a nearby plaza.
The area is mostly locals (no tourists) close to a school, and feels fairly safe. Would recommend getting off at Metro Station Poble Sec and walking south Caller Blasco de Garay.
