We enjoyed our stay at Katarina's apartment. Katarina was very helpful in all the preparations before we arrived in Prague.
We did not meet Katarina herself once we arrived, but were looked after by the commercial property managers. They were responsive and helpful when we had issues with the heating and crockery supplies in the apartment. The location was good, a moderate walk to many sites and to access the public transport. The apartment is on the top floor so there are lots of stairs, but the very small lift also worked most of the time.
