Amazing!both,the host and the appartement.Best place to stay if you look for a central,but authentic place a bit away from the main tourist stream.The appartement itself makes you feel like in your own home.Katka was very flexible (she had to wait for us) and welcoming.She knows the city well and has some great recommendations where to go out.Whenever back to Prag,we will stay again at Katka's place.
