We loved the hotel - the apartment with ensuite sauna and whirlpool / four poster / was outstanding for a '3 star' - we would rate it higher. The breakfast (included in tariff) very good quality and generous. The restaurant meals were both good value and delicious, although slightly let down by the occasional chipped plate/dish!
If you have your own transport the Hotel is ideal for much of the Czech Republic. As a base for Prague via public transport it's for the more adventurous (it suited us). You need to metro out from central Prague then catch the local bus. Allow an hour for this metro/bus trip - and the last bus is at 9 p.m. Taxi would be fairly expensive.
Staff are very friendly, as yet have little English, but this doesn't seem to matter. We got by with our very basic German.
Excellent experience

First hotel I have ever been to in this class that were "unable" to provide an extra pillow although medically needed by a sufferer of rheumatoid arthritis - the beds being quite hard in the private apartment where we were placed. No air conditioning, the extractor in the WC shower did not work, clean sheets only after 3 days. Breakfast was passable although they were slow to replace items consumed by earlier birds and slow to clean the tables.
Being out of town it's almost one hour to get in by local bus and metro for a cost of 36 ChKroneas for 2 people, as opposed to the 1100 charged by hotel taxi to the town centre.
But the staff were friendly but reserved, not volunteering information, maps etc, and few spoke much English.
I wouldn't stay there again.
