I stayed 2 nights in Juan Pablo's Place and it was the perfect one person solution in Madrid. The room is small but cosy, clean and quiet. Next to the room there is a private bathroom and you can enter and leave the house without seing anyone (if you don't want to). The house is well situated next to a metro station and in one of the most authentic neighboorhood in Madrid. the communication was smooth and easy and Juan Pablo was really helpful, sharing some tips to enjoy Madrid the best way possible during the hot summer. I would definitely recommend Juan Pablo's place
