Location is fantastic and it is great mid-range place to stay if you want to explore old city of Prague. We were there for 3 days and we did not need any public transportation and everything was reachable on foot.
We were welcomed with a small bottle of wine. Alas! we do not drink alcohol so we left it as it is. The room was very clean. Since we stayed for 2 nights only, we are not sure about the cleaning processes.
