Suso's place is cozy and it has soul. The deco is charming, funky, full of homey artefacts, you won't feel in an Ikea showroom! The couch & bed are incredibly confortable and there is everything you can possibly need. Madrid is my second home, and the Chamberi district is my hood, away from the more touristy areas. Without hesitation, I strongly recommend Suso's home.
The only drawback is the noise, it can become quite intense at night on weekends, light sleepers don't forget your ear plugs! Enjoy!
