This apartment was fantastic -- what a great experience. The space is beautiful (even the very nice photos on airbnb don't quite do it justice) and it is very well-equipped: comfortable bed, kitchen nicely stocked with everything necessary for cooking, etc.. The highlight is the spacious rooftop terrace, which has breathtaking views. Location couldn't have been better -- it's in a vibrant neighborhood within easy walking distance to many of the parts of Madrid we most wanted to see.

I should add that we stayed at Paz's apartment during some very hot days (90 degrees Fahrenheit) and didn't have any problems -- there is a small air-conditioning unit as well as a fan, and we were able to keep the space pretty cool.

Overall, we definitely felt that we lucked out with this wonderful apartment -- highly recommended.
