PROs: conveniently located and well connected if you enjoy being in a touristy area. Newly renovated interiors. Very clean.
CONs: Glitchy self check-in app caused delays in the process. Early check-in request wasn't answered.
Small room at the ground floor, not bright, absence of hangers or closet in the room. Room1 window facing a community garbage can and a Burger King where you can read their menu and see people dining inside. We cancelled the reservation and left the morning after arriving as we didn't feel it was the right way to experience Madrid. The host kindly accepted a partial refund, totalling one night stay at 208€.
I'd feel ok for 1-night business stay if you pull the curtain, or if you get the much lower rates shown on the paper by the entrance (50-60€). We went at Easter and pricing was 2,3x.
