We had a great stay in this apartment. It's central location makes it the perfect base for exploring Madrid on foot. We were minutes from the La Latina metro, and a convenient luggage-holding company called Lock & Be Free (?), and next door to some little shops where we could get breakfast and a sim card. The apartment is a simple but comfortable and clean studio. As stated in the description, it is up four flights of stairs (no elevator) which was not a problem for us. We would recommend.
