Very nice to meet with a larger group of people. The waiters were, so far, quite friendly. The service is good, the food delicious (at least, the antipasti plate I've had the last time). Their iced tea is homemade with a strong hint of mint, which I actually liked.
All in all a good experience. Comfortable, relaxed, uncomplicated - just as I like it.
(even though a bit on the pricey side)

The Charles Bridge and other sights are in walking distance (5 minutes). Not far away (also about 5 minutes walking distance) is a metro station, so basically every sight in Praha can be reached in almost no time from the hotel.
The rooms are actually quite roomy (old convent) and nicely decorated.
Here's the list from their webpage:
* King Size Beds
* Imflammable Materials
* Smoke Detectors
* Air Condition
* Minibars
* Comfortable Working Desk
* Internet Access Cabel / Wireless
* LCD Screens with Sat TV and DVD Player
* Direct Dial Phones
* Large Safes for Notebooks (with Electric Outlet)
The beds really are king size, the desk is definitely nice to work from, the the internet can either be accessed by the PC in the entrance hall or from each room (simply ask for the login data). The bathroom is very spacious and the hotel employees very friendly. In the evenings shortly before and right after christmas punch and cake were offered in the entrance hall.
I am not sure about the "inflammable materials" but other than that, what they've listed is there and easily available.
The breakfast buffet can be accessed until 10 am (they seem to know that vacationers like to sleep in) and offers a nice range of muesli, toast, jam, honey, fruit and warm dishes.
Check out the homepage for the rather interesting hotel history.
