My two colleagues and I stayed at this apartment while our remote team had a week-long in-person meeting in Berlin. We chose this place because it was close to our co-working space and it offered enough space for the three of us. In this regard, we are very happy and could have even accommodated another person.
There are a couple of specific things I'd like to mention: We stayed in early February and took a while for the place to warm because of the large walls and areas. During the nights I felt it was a bit chilly downstairs. Also, the place has only a single window which can only be opened a tiny bit. Therefore, letting in fresh air was very difficult. Finally, since we travelled at our company's expense I asked for an invoice. That was 10 days ago and I have yet to receive it (I was told that it takes "a little while"). We travel regularly for our company and usually receive the invoice within 48 hours. Given how professional everything else was, I expected a faster response.
