+++ Super central: 2' on foot from the Opera meteo station, ~5' from la Puerta del Sol, Plaza Mayor etc.
+++ Plenty of shops, bars, churrerías (incl the famous San Ginés, 3' away), jamón shops etc.
+++ Easily reached from the airport via metro, frequent service
++ Welcoming, helpful staff.
++ Very good internet (in my room, no. 6).
-- Noisy room. Every 10' or so a noise started and lasted 10-15' seconds, like a train going by under the building.
- Very small room (but normally small bathroom): space for bed leaving passage on 2 sides of the bed. Not a prob for me as I stayed only 3 days and was out all day.
- No proper wardrobe, only a small niche. If I had had more than a cabin trolley, it would have been very cluttered.
- Expensive for what it is, but in line with prices in centrsl Madrid.
