I came to visit Madrid for a few days with two friends in December. We had a very comfortable and enjoyable stay at Juan's place. We were at walking distance from most places that we wanted to visit. The place was also very clean and well stocked with kitchen supplies and amenities. I would only mention that it is located at the top of 6 flights of stairs, which was manageable for us, but may be difficult if you are carrying a lot of luggage or have mobility concerns. Overall, a great stay - thank you, Juan!
