Katka is a great host. She greeted us in the apartment and gave us all the useful information. The apartment has great location, walking distance (1 mile or less) to old town, castle, and all the attractions. Quite. Also very close to Tesco if we need any thing. The view is very nice. I'd favor this location over Old Town to stay away from the tourists.
We would definitely stay here again next time we visit Prague.
