Karmen’s place is perfect for a short stay in Madrid. The location is excellent, super accessible by Metro. There’s a Carrefour Express not too far away, so you can very conveniently buy groceries. Bedding was clean and quite comfortable. There is not much light though in the flat - it was basically pitch black even in the middle of the day as there is only one small window which opens up onto a small closed courtyard area. Overall it’s a great place if you plan on doing lots of sightseeing and don’t mind not having natural light during the day.
