We spent three days at Josef's apartment and were completely satisfied. We arrived at a very clean room located just a few minutes from the old town square. Opportunities for shopping and groceries were nearby (1-minute walking distance). Coffee and tea helped us getting out of the comfy bed in the mornings.
Josef also had great recommendations for restaurants, bars and sightseeing we were very thankful for.
He really helped us spending our time in prague as good as possible and responded to any question we had within minutes.
