Good stay overall. Communication was fine and check in seamless. Location is fine as well.....about 12 mins walk from Plaza Mayor and about 15 mins walk from Atocha train station in a very multicultural area of Madrid which we actually liked - home of a bunch of interesting restaurants with various cuisines from around the world. Conveniently a two minute walk away there is a carrefour supermarket open 24/7.
Inside the apartment music can be heard till late in the evening although closing windows nearly cancels all the noises. The apartment has all the basic amenities......however I would suggest to the host to include a few kitchen cloths and some kitchen towels.
