The host is great, he was there although we arrived quite late. The locations is also great, walking distance to Matadero and to other great places to eat. Close and easy access to everywhere with the metro. Very clean and comfortable beds (except in the living room).
The only thing that you don't see on the pictures, at least we did not realized, is that there is no privacy really between the rooms. There are sliding doors and form of open space in the apartment. But I would still recommended it :)
