We loved staying at Moncho's place. It was clean and quiet, and very convenient to Atocha train station, as well as a nice walk to all of the major attractions in Madrid. I slept very well :) Communication was excellent and wifi worked very well. I would stay here again
A word of caution - my phone was pickpocketed between the Metro station and the apartment. This is not a reflection on this listing as the apartment itself is very secure. I believe we were followed and this could have happened anywhere in Madrid. Just a reminder to keep your guard up and secure all of your belongings in a theft-resistant bag.
