Mercedes was a very nice host! My flight got in late but she was waiting for me and very helpful when I finally arrived. The apartment itself is clean and comfortable. It is a good apartment for one or two people for a few days. The location of the apartment is in a fantastic location right above retiro park. The metro is a few blocks away and the main attractions are very easy to get to. Overall it is a great apartment and I would highly recommend it to anyone visiting Madrid!
