We had one of the Premium rooms with a terrace.
The room was spacious, bed was very comfy and the shower was great and well designed - good pressure, plenty of room and well contained (i.e. no risk of water puddle waiting for you as you come out).
The amenities were more than adequate.
We found the room very quiet (even when facing the main roads below). And I enjoyed my espresso on the terrace in the cold and sunny Winter Madrid.
The hotel is very well located, plenty of good spots within 10min walk or the metro station next door).
We didn't have the breakfast on site so can't comment there.
The staff was very professional and friendly, with special thanks to Alicia for accommodating our various requests on the last day, all with a smile.
We would definitely stay there again during our next visit to Madrid.
