We were only in Prague for the one evening collecting some friends from the airport to travel onward to South Moravia, Jana was very helpful when we booked the apartment, communication was excellent. The apartment was in a great location about 5 mins walk from the main Old Town square. The facilities were very nice, we did not meet Jana but her son looked after all our needs. Just be aware that this accommodation is on the top 3rd floor and there is no lift.
Highly recommended, we will stay there again next time we visit Prague.
