My boyfriend and I drove here for a weekend trip from Berlin. It was perfect for the two of us as neither one of us wanted to be in the city center. The flat was about 20-30 minutes away by tram from the city center (FYI you can buy tickets on the tram, and/or at a store like Ksenija suggests on an info sheet she leaves in the flat).
Ksenija responded quickly to my messages/calls and was very friendly. Her lovely mother met us at the flat and gave us a set of keys (she didn’t speak much English, but that wasn’t a problem because everything was pretty straightforward).
The one slight drawback was that figuring out parking in Prague is a bit of a nightmare. Street parking is a bit confusing and it’s rare to find a free spot. The parking lot that Ksenija recommended on the aforementioned info sheet was really run down and prices had gone up (which she told me when I later asked her about it), so we parked the car at P+R Holešovice (7, Praha, Holešovice, 170 00 Praha 7, Czechia). It cost us 380CK/14,70€ for just under 72 hours. It was a few tram stops away and was well maintained and had an attendant there during the daytime.
Overall, we thoroughly enjoyed our stay at this place! The huge tub and and kitchen area (with all of the most important cooking tools) were standouts for us.
