Gonzalo's place it's really worth staying in.The location can not be better in one of the most beautiful areas of Madrid.,minutes to the Plaza Mayor, Puerta del Sol, The Royal Palace.It's the oldest part of the city and just to walk around the neighborhood is a pleasure.The apartment has lots of light and is very quiet.There are a lot of restaurants, places for tapas and cafes near by.Also there is a local market,El Mercado de la Cebada, three minutes from the apartment as well as supermarkets and shops near by.
We stayed for four weeks and were very confortable.The wifi works perfectly also, something that it's always very important for us.
I highly recommend Gonzalo's place
