Lived in this apartment for 2 months and have a solid grasp of the place. Modern building, fast & reliable internet, and loved the desk / working chair.
Location is excellent! If you know nothing about Prague, don’t be deceived by the distance from Prague 1 on the map. Train, tram, and grocery store readily available.
Really the only downsides were sometimes being able to hear neighbors and the shower being handheld only. Very minuscule downsides that you probably won’t even notice.
Finally, Katarína is excellent! Responsive, helpful, and respectful host. 10/10 recommend for short or long term stays.
