Communication with host was great after we booked the room. She was nice to us when we came and we appreciate her waiting for us very late (past 12.30 midnight with late check in fee). She is good host in general.
The place is an apartment with couple of rooms for airbnb. Toilet, sitting room, kitchen are all shared with them and all guests.
We did not finished our stay (checked out after first night) because the 3 bed room was directly across the road and we could not sleep with noise from outside (people drinking/ talking loudly, etc all thru the night). The location is also quite dodgy for foreigner (2 asian females) not aware of this part of barcelona. Other guests (guys watching fc barcelona game the next day) on apartment above seemed to be fine with it tho.
