We had a great experience in Czech. The room is exactly as described in the pictures and location is perfect, 10 mins away from the castle in one direction and the same time if you want to cross Charles bridge. Also public transport is a couple of blocks away. Despite we didn't spend much time in the house, Niko was very receptive to all our queries and replied very quick. We will definitely stay there again in our next visit to Prague. Thanks Niko!
