The room it's very basic, clean and with comfortable beds. The location is very good, we did our days walking from there to a lot of iconic spots in Prague. It's close to kiosks, kebab's places and even bars (there's one you can hear from the room).
If you like 80's and 90's and some latin music, you won't have problem with the noise in the night.
The breakfast was better than expected and very complete.
