This was the perfect location for our one-night layover in Madrid: we were travelling from Atocha to Seville the following afternoon. The apartment was very clean and the facilities were perfect for our short stay requirements.
Carmen - and her assistant, Carmilo - were very patient waiting for us for your patience when we arrived late then got dropped off at the wrong end of Calle de Méndez Álvaro (the taxi driver dropped us at Méndez Álvaro Estación Sur)!
Also, we loved your dinner recommendation, Cervecería Cafeteria La Ochava, just around the corner from the apartment block.
We found it very easy and cheap to leave our suitcases at the left luggage at Atocha, behind the tropical garden.
