Pros: Very clean, spacious, and comfortable for a group of 10. Communication was excellent.
Cons: The check in process is too complicated. While we were very close to many tourist attractions, the listing is not located in a very good area of Madrid. The square smells of urine and - to give you an idea of safety issues- an older man asked my 60 year old mother, who dresses conservatively, "how much do you cost."
