You feel like a guest in a flat of your friends - it was interesting and nice :-) very good location - you can reach all sightseengs by foot. There is an elevator in the building so you don`t need to carry your luggage on yourself.
There is no airconditioner!!!!! It was plus 47 in Madrid during the days and plus 33 in the nights - it was impossible to sleep without airconditioner. It is a hostal so they don`t have a restaurant or breakfast room so you will need to have a breakfast somewhere outside.
