Oksana is a great host, very communicative. My fiancee and I really enjoyed our stay and made full use of the kitchen. Note that the apartment is quite small, there's very little floor space so those with large luggage may find it tricky, and as the apartment requires stairs either way you enter, large luggage is not advisable.
Transportation passes were provided with our stay, which was very helpful and allowed us the freedom to explore -- FYI if you plan to take public transportation to get to the apartment, make sure you have CZK coins (24CZK for a single trip) or a wifi enabled credit card, as the ticket machines do not accept cash notes. Also not every station has a ticket machine.
As some others have mentioned, there's not much of airflow in the bathroom/apartment in general, so if you're visiting in winter that may be a slight issue as there's also condensation gathering all the time. The bathroom is quite spacious though and there were never any smells.
Highly recommend!
