Great place in the busy centre of Madrid - close to everything, you won't need communication for sightseeing. The street during the weekend was loud, I think there are people there all night - might be too loud for some people. Not music or cars, it's just a very busy pedestrian street. For me it was a nice sound to fall asleep to.
Room is small, but nice, has everything you need. Bed comfortable. Flat is warm, even in very cold winter. The elevator worked 50% of the time, but Giselle warned us about it before arrival, that there is some unplanned conservation during the weekend.
Giselle is a great host, we felt welcomed.
Great value for this price, if you want to be in the centre of Madrid.
