i stay in Roberto's house for nine night,the room is very comfortable with a private bathroom.my plane was late for4hours,and i arrived at the house at3am,Roberto waited for me and didn't complain.he is very nice and patient,he print the maps for me,and made phone calls for me to change the time of the shuttle bus.AND,his house is located in the center of Madrid,it is really really convinent to visit any places from his house,because the metro station is only about 3 minutes'walk.the price is really cheap considering the perfect lication of his house.
