Stayed in a single room. Private, cheap and exactly what you pay for. A clean bed with a lock on the door in the heart of one of the world's cultural centers. It's a small hotel so there's 24 hour doorman which is a huge plus. They will hold your bags if the room isn't ready, so you can explore the city.
Four stars because the small (private) bathroom smelled a bit musky. Could use a better vent. And no A/C. Bring your own soaps!
