I stayed at Uta's place for a little over three months, and I had a wonderful time. So many great things to say - I don't even know where to start. First, the location. The apartment is located in one of the most trendy and up-and-coming neighborhoods in Berlin (Bergmannkiez). In addition to being surrounded by nice and eclectic cafes, restaurants, bars, food markets and thrift shops, Bergmannkiez is a very peaceful and picturesque area. It is also centrally located, so you are well connected to other boroughs in Berlin.
The apartment is fully equipped for a long-term stay like mine. It is fully furnished, has a washing, iron, microwave, pots, pans, TV etc. - basically everything you need to feel comfortable for a long stat. The apartment is not flashy, but it is very cosy.
Lastly, Uta is a great host. She is communicates very well and was always checking up on me. Can't recommend this place enough. I will be back for sure.
