This hotel was booked for me through one of the universities so I could attend a work meeting. The location is great - not only right by the Puerta de Toledo, but also a short walk to other places of interest. And a Metro stop, as well.
Staff were very good - check-in was friendly and efficient. The hotel has clearly been refurbished recently and looks quite modern. My room was on the 7th (top) floor. The room was fine, except that the only window is a skylight - not to my liking but I was only there for a short stay. Comfortable bed, bathroom fine - great shower with good hot water.
My biggest gripe, and hence only 3 stars, is the poor sound insulation. Unfortunately, the door to the room offers absolutely no sound insulation from the corridor - every footstep can be heard, as well as doors opening and closing. Other guests weren't noisy but it felt like I was on the corridor rather than in my room.
Similarly, the sound from the neighbouring bathroom was very obviously audible - to a level that what I heard was rather more than I cared to discover about other guests' digestive processes (and I'm sure their feeling may have been similar...). This is really a big minus for me - even if earplugs firmly in both ears, there was still more noise than I've encountered elsewhere.
Perhaps it was the fact that this was on the top floor and other rooms are less bad, but this does put me off from returning, despite all the other positive aspects.
