Great space to explore Berlin from. We enjoyed staying in Kristina’s flat. It is small, but fully functional as a base from which to explore the city.
The only problem we encountered was with the WiFi, which stopped working on the second day.
It is worth noting that this is a ground floor flat facing a busy road, so some level of noise and light was present all night. Didn’t bother us, but if you are sensitive, bring an eye mask 😊
