This is a lovely apartment and very comfortable to stay in. I was made to feel very welcome by Mercedes and there were nice things for breakfast already waiting for me, including ground coffee and milk. Communicating with Mercedes was very easy and felt that they were there and ready to help if I need them. There are plenty booklets on things to do and see, which I found very helpful. It is in a great location with a nice atmoshere with nice bars and restaurants in the area. I found it very easy to reach every where by foot but if you need the metro it is in easy access just 5 minutes away.
If you are thinking of coming to Madrid this is a good place to stay.
