Fantastic location, right outside are a ton of bars and restaurants and you can see the Dome from your window :) The place is clean and has all the essentials you'd need. I found the bed very comfy. It's super easy to pop in and out between sightseeing since it's so close to all the museums.
FYI: The bathroom is small, and the bath is one where you sit down to shower. Not an issue for me, but for tall people who need a lot of space, that might be a consideration. Also, the bathroom is separate from the living space, so you need to cross a hallway (eg take two steps) to reach it. There's a separate key for it.
Location was fantastic, and the room was an excellent retreat above the bustle of the street. I'd stay again gladly :)
