The Katharina apartment was charming and full of character. The bedroom was cute and cosy - along a sort of hallway overlooking the courtyard. The atmosphere was vibrant - a coffee/dessert/beer and wine cafe in in the courtyard downstairs and there is a 'hidden' bar in the cellar (verrry cool). We went to the bar one night and the bartender speaks flawless English and he was great to talk to. The location is a block from the St. Charles bridge - convenient so that we crossed it a few times. The neighborhood was charming and close to many specialty shops and cafe/restaurants. There were no hassles or issues with the apartment....everything was good. One disclaimer I will give and that is for people that are sensitive to cigarette smoke.... in Prague (and many other parts of Europe) smoking is allowed in outdoor cafes and bars. In the courtyard people were smoking and the smoke would drift up at night to any open windows. Ideal? No. Tolerable because the apartment is so wonderful? Yes.
