I stayed in Pedro's Apartment when visiting Madrid with my Mom.. At check in we were greeted by Bozena, she was very kind and warm. check in/ welcoming process was quick and easy as well as check out. The apartment is located on the 5th floor- accessed through a center patio walk to the elevator - elevator is an old model but its very safe from my experience. The place was very clean and cozy, the beds were two spacious & comfortable twins. the building is secured as you need a key to access the lobby area. LOCATION!!!: located next to La puerta de atocha & Parque De Retiro (two must see locations in Madrid) walking distance to everything else.. we took a taxi a couple of times when it rained but its walking distance to everything we walked to El palacio Real, La Puerta del Sol etc, if you dont feel like walking an Uber ride is under 10 EUR. I would recommend this place and host to anyone visiting Madrid, perfect location/clean and accommodating host, reach out to Bozena & Pedro with anything you need and they will be happy to help.
