Lovely flat - nicely furnished and comfortable, and really well situated - away from the tourists but still only 5 - 10 minutes on foot from the main sights.
Note there's a mini supermarket a couple of minutes away - just turn left at the door, then left on the road and it's a hundred metres away on the square.
And the Kolkovně bar across the road serves some of the best draught Pilsner - and a mean goulash :)
