Diego's place is very clean and has all the basics. The best value is that it is located close to all the places you will want to visit in Central Madrid and not far from the train station either. If you are planning to spend most of your time checking out beautiful Madrid, this place is perfectly fine to come back to in order to rest or sleep! I noticed it has a washing machine which is a nice convenience if you are on the road for a while! The back room is pretty quiet at night if you close all the windows and doors.
