Very centrally located which made exploring Madrid very easy, the staff were lovely and really helpful, the bed was very comfortable and the bathroom facilities were good. Always very clean as well. Only issue was that it wasn't as social as it was made oit to be, but this wasn't helped by the poor weather meaning the rooftop was essentially out of action. The mixed shared dorm being on the street rather than in the building meant that we had some disturbances from passers by making noise late at night, but that was only brief.
