We (couple) had a wonderful weekend in Madrid and stayed for two nights. The appartment of Max is perfectly located in La Latina and you can do from there everything by foot if you want to. The appartment is small but has everything you need. It was well prepared and Max gave us a lot of hints and explanations. The only thing to mention is that the bed is not too comfortable and if you have a light sleep you hear noise from the street or the neighbours in the building - but for us that would be no reason not to return. It was a great place.
