Pros : great location, calm despite the busy neighborhood, the agency person who did the check-in was really nice.
Cons : the major one is that the toilet is open to the room, with no door or roof, only a sort of curtain separation. This was more intimacy (and smells) than I certainly wanted during this trip. The listing only mentions that the "shower" has an open roof to the room.
However, it is mentioned in a couple of guest reviews so it's my fault for not having read all of them. But it's something that's so unusual that you don't even think about checking whether the bathroom has a door.
Another con is that there are no light blocking shades, only white curtains that let in 90% of sunlight. This can be an issue for light sleepers like me, especially during summer in Barcelona when sun rises early.
