Nice Apt on the north side of Prenzlauerberg with many cafés and restaurants close by, good transportation in the area. The Apt. Itself is not very personal (more like what you would expect from a hotel room), but functional and clean, good to relax and sleep after a long day in the city.
The check in with Ellen did not go smooth, since the address that we thought we needed to pick up the keys had already closed, and it was very late, so we had to book a hotel room the first night. Ellen changed the address, but this was easily missed in the very long e-mails that she wrote! So when you book, please make sure that you are on the same page to avoid a situation like this.
