Pedro is a great host! He replied quickly and was very flexible in the check in.
The place is just like in the photos, small but has everything for one person short stay. Coffee machine with coffee capsules was a nice detail! The place is super clean, and worked out well for my business travel as I wanted to have a more homy feeling for the trip.
I don't have anything to complain about, but for a person who feels always cold, I felt a bit chilly in the apartment as there is just one heater and Madrid can get quite chilly in the Autumn/Winter. Also the walls in the building are not the most isolating ones, so if you are sensitive to noise while sleeping, like me, I should warn about the noise as you can hear everything from a sneeze to proper conversations from the next door neighbours.
