Four of us stayed at Álvaro’s place for three nights. The apartment was lovely, very clean and well equipped. The beds were comfy, and having two separate bathrooms made sharing the apartment very easy.
The location was great; there was a supermarket only a few minutes away, as well as some great bars and restaurants. The Palacio Real de Madrid was only about a 10 minute walk away, and the Parque de El Retiro about a 30 minute walk away.
Al four of us would highly recommend Álvaro’s place for a short stay in the city.
