I'll definitely come back on my next visit to Madrid. Perfect location, really convenient check-in and check-out arrangements. (I was able to leave my suitcase after checking out and then pick it up in the evening.) The room was great, with lots of storage space. Everything felt very new and clean, I appreciated the luxury shower, high-quality furniture and super comfy bed. If you're a fussy sleeper you should bring ear plugs – the street can be a bit noisy and you might hear other people in the house banging doors etc. Still, highly recommended!
