What an amazing apartment, the photos are true to life-however they don't show the height of the ceilings which add to a very spacious feel of an already large living area. The bright natural light in the bedroom is truly beautiful, perfect for those days when you don't want to leave the apartment, which is likely to be many!
The apartment is in a period building, a lot of the original features have been retained in the apartment such as the floor tiles in entrance and kitchen, bath etc. To some these may look a little tired however I found these to only add to the character of the apartment.
Located in the high end shopping district of Madrid, quieter than Lavapies etc at night, but perfect for me.
Entrance to the flat is down a dark dingy passageway and up 4 flights of stairs as others have mentioned, however the climb is well worth it when you get there.
Highly recommended, I would stay here every time I visited Madrid.
