What a lovely place in the heart of it all! Ruben was an excellent host and very easy to communicate with. He was able to accommodate my cousins' early check in and assisted us during our stay as well. The place looked exactly like the pictures, and was very comfortable for the 4 of us. The location can't be beat! The apartment is a few minutes walk from Plaza Mayor and Puerta del Sol, and about 20 mins walk to the Atocha station. Very close to fantastic eateries and Calle Cava Baja for delicious tapas. I would recommend this place to others, and if we come back to Madrid, will surely look up Ruben's place again. Gracias Ruben!!
