Carmelo is very friendly and it was easy to communicate with him prior to and during our stay in Madrid. Carmelo was very flexible with the check-in and check-out which helped a lot. When we arrived he provided us with maps and took the time to tell us a bit about madrid incl. some recommendations on what to do, etc. The flat itself was clean and had everything we needed during our stay. The location is quite central (~20 mins to gran via by foot) and in a safe, quiet neighbourhood. There are many cafes, bars and restaurants very close. we had a great time and can definitely recommend Carmelo's apartment for a city trip to Madrid!
