We stayed here for 3.5 weeks, and couldn't have been more pleased with this sweet apartment, the location, and especially Francisco & Christopher! From the beginning they were communicative and immensely helpful, and they remained in constant touch throughout our stay, offering suggestions and responding to (very minor) problems immediately. Mike, who checked us in and helped out later with maintenance stuff, was also very nice. We felt very well cared for! The apartment is lovely, spotless, and had everything we needed for a comfortable stay. The neighborhood is great. We've previously stayed in more "hopping" areas of the city and enjoyed the more low-key, local vibe here. There are plenty of cafes and restaurants and a half-dozen grocery stores within spitting distance. The Metro is 2 blocks away and there are plenty of busses. But best of all is having Retiro Park right at the end of the street! All the museums and touristy stuff is a lovely 15-minute walk across the park. Incidentally, a reason we chose the apartment is because it's close to the AIL Madrid Language School; if you're taking classes there this is the perfect spot (the apartment even has a little desk). Many thanks to Francisco & Christopher for an excellent experience!
