My wife and I stayed in Frantisek and Erika's apartment during our four day stint in Prague. The apartment itself is absolutely wonderful and it really enhanced our experience of the city. The location cannot be beat as it is centrally located and within walking distance of all of the hotspots while at the same time feeling secluded from the hustle and bustle of tourists. The apartment has all of the amenities you would want and I think the photographs of the terrace views speak for themselves.
With respect to Frantisek and Erika as hosts, they went above and beyond to accommodate my wife and me during our trip. I had indicated that we would be arriving early by bus but that the check-in time would not be an issue. Notwithstanding, Frantisek and Erika, unprompted, offered to let us check in right after we arrived.
We look forward to returning to Prague in the future and hope to have the chance to stay here again.
