A lovely apartment in a great location! We loved the La Latina area, everything is a walk away, and there is lots on the doorstep as well, including supermarket, deli, bakery, great coffee shop (Calle de la Ruda), restaurants and the Sunday market. The tube is a minute away from the apartment (I would recommend taking it to Chueca and the San Anton market) but you can easily walk away to many of the main attractions in Madrid. You should definitely stay at Marta’s apartment!
