We stayed at the apartment for 3 days. The apartment was much better than you can see at photos. This is small studio with its own terrace, thoughtful interior, comfortable kitchen (with all necessary utensils and appliances) and a sleeping area. It was very clean, the only thing that was a little embarrassing was the low side in the bathroom, so you should be careful while taking a shower to avoid water from entering to the floor. Bianka helped us a lot, told how to get to the apartment, then to the city center and was very welcoming. The apartment is located near the train and tram stations, so there are no problems with transport. We really liked it and if we'll come sometime to Berlin we would like to stay there. Big thanks to Bianka for everything!
