Emilio's place is very centrally located with plenty of food and shopping around. It is under a 5 mins walk from the nearest station, Sol, which is a major central station with various connections/ lines available.
Emilio was also very communicative and offered a lot of good tips. He provided a map and the house was spotlessly clean, and very nice and modern exactly like the photos.
The house is 2 floors up a narrow staircase, so just a gentle heads up to those who dont travel light. But not a major issue at all. Emilio helped with the way up and we made it down upon checkout with no problems, just be careful.
We were 2 hrs late for our scheduled check in time due to traffic (beware of the madrid city jam!) and timing miscalculation and Emilio was super nice and patient about it! Really wonderful host! We hope to be back soon :)
