Amazing location, less than 2 minutes walk from Charles bridge and around 4 minutes from old town square.
Rooms are nice and big enough, we got a delux room and was really nice!
The only maybe negative point will be the cleaning, for a 4 start hotel I was expecting clean bedsheets and towes everyday, but that did not happened, we got our bed fixed everyday but no clean sheets.
There is no restaurant in hotel, they do only breakfast which is 10 euros extra. But thats not a big of a deal as there are plenty restaurants close by.
For the rest, amazing location.
