Zdenka's apartment is clean, spacious, and has all the amenities needed except there is no air conditioning as stated. There's a ceiling fan in the bedroom. Unfortunately when I visited, Prague was hot and it was a bit uncomfortable with just opened windows and a fan. I'd imagine in any other season or a cooler summer, it'll be perfect
The apartment has an old-style feel with high ceilings, parquet floors, and nice furniture. It's on the third floor with an elevator in the building. Its location is ideal for local transportation (tram is a short distance away, metro at Anděl, walkable) and it's a walkable distance to the city center too.
Zdenka, though with limited English, is a gracious, efficient host who met me on time at both check in and out. She provided clear instructions about the apartment and had load of tourist information available.
