My favorite aspect of the apartment was the location. I never took public transportation, though it was easily accessible, because the apartment is so central. Vadim was there to greet me upon arrival, and spent a good amount of time giving me an overview and tips for the city.
If I were to give any advice it would be to bring ear plugs for the noise of being in an old building with neighbors, and perhaps an eye mask as light from outside and from other guests really illuminated the bedroom.
As a solo traveler I was also more than pleased with the security of the apartment. Your room of course has its own lock, put the apartment complex also has security and it’s own gate.
A truly wonderful stay and a great apartment for any Prague adventurer.
