We had never been to Madrid before. Our criteria was to have a unit that was walking distance to the historic areas of Madrid. This place was terrific. Being on the Plaza Mayor was energizing and enjoyable. The apartment was clean and spacious. Our hosts were very communicative and supportive. One note, there is an elevator but it does have 6 (approximately) entry stairs inside the lobby. Not a big deal for most but good to know.
Lots of resources close by.
Highly recommend!
