Overall a really good value: excellent location in the city centre, easily accessible, very clean and includes all basic necessities (towels, kitchen, and even air conditioner). Lorenzo waited for us at the apartment when we arrived and the check-in process was very easy. Couple things to note if you plan to stay there is that you have to climb narrow steps (without a proper railing) to get to the bed and that it can get get loud at night since the apartment is on the ground floor and people in Madrid walk or hang out outside well into the middle of night. Otherwise it was perfect.
