The place was super clean and convenient, looked like the pics, and very close to transit and reasonably walkable from sights. There is a nice bakery down the street and a 24hr grocery nearby. It's a good value.
However, it is very loud. I know Madrid is a city that stays up late, but the club a few doors down the block is booming til 4 or 5, with two dozen people outside and shouting some nights. The neighbors next to the bedroom have a handful of loud kids who were squeaking their recorders one day. They were quiet at night, but the club wasn't. I had my earplugs in, white noise blaring from my phone, and closed the window covers. Not for light sleepers.
