The place worked for me since I was just staying one night in Madrid. I had a late flight to Madrid, arrived to the apartment at around 23:30 and was greeted by Carmen who gave me pretty clear directions on getting to the apartment. I didn’t really interact much with her but she seemed friendly. The room was and looks just like the pics (doesn’t have a lock if that is something you look for). The bathroom didn’t seem super clean to me (mop and bucket right next to shower which seemed odd). Overall I think for the price and brief stay, it worked for me.
