Flat was well located in Malasana (hipster part of Madrid). You should know that this is a communal housing with multiple rooms and a shared kitchen and bathroom.
Pros: Good place for going out and eating in the area and Madrid is easy 20 minute walk around the city. Luis is responsive and allowed us to leave our bags after check out to explore the city more. Apartment is clean
Cons: Very noisy street below at night during the week. There is no door on your room, and the curtain does not cover light coming into the room that well making sleep a bit difficult when other people in the apartment turn on and turn off lights throughout the night. The room is also located next to the bathroom and you can hear bathroom sounds pretty loudly.
Not a bad flat, but there could be improvements.
