The apartment is very well located, spacious, has everything, which you can see on the pictures, however it probably needs some renovation: in reality it looks a bit worn down and not as fancy as on the pictures. Furthermore, it can be quite noisy due to neighbors, but this isn’t the fault of the host, it’s more the building and the walls.
The sanitary sewers are currently changed on the street, so there is a construction nearby, but this is basically everywhere around Eixample.
Overall a very good experience, but maybe a little bit overpriced.
