Great location, situated in la Latina, one of the most beautiful neighborhoods in Madrid. Still very close to the city center, you walk about 5 Minutes to Plaza Mayor, but also with other "trendy" neighborhoods like Lavapiez in the same walking distance.
The room and the apartment in general are very tidy and clean and Ales is just a wonderful host. She's a very lovely and funny person and always ready to help you out... plus she has probably the most cutest cats ever! So I definitely can recommend you to spend your time in Madrid here! I'll try to come back in the future for sure.
