Karen's flat is great: beautifully decorated, spotlessly clean and very comfortable. It's also in a terrific location! Practically right outside is the amazing revolving sculpture of Kafka's head, plus a great new development including supermarkets (Tesco and Billa) and a selection of places to eat. Prague is a very easy place to walk around but while we were there the temperatures were up in the mid-30s so we were also glad to take advantage of the terrific transport system, which is also easy from Karen's flat. Her directions from the airport were also spot on, no need to take the crowded airport bus which had a long queue when we arrived. Karen and her colleague Branka made us feel very welcome and definitely helped to make our stay in Prague very enjoyable. We would love to go again (in cooler weather!) and would definitely like to stay in Karen's flat again; highly recommended!
