Location was very good. Metro Histafrancs and supermarkets located within 50meters. Every POI can be accessible by mass transport. Pl Espana and magic fountain of Monjuic are walking distance.
Elevator is useful for heavy luggage.
Security system was reliable and the neighbor was safe.
This was my first experience of airbnb. So I cannot compare with others.
There's minor disadvantages.
1. matrices of beds were not soft. It depends on personal preference though.
2. A little bit noisy at night because of the traffic. But shutter screen can reduce the noise.
