I stayed here for a work trip lasting about one week. I didn't spend much time in the apartment other than sleeping. It was a 5-10 minute walk to Martin Gropius Bau and a little more to Potsdamerplatz! It was clean, comfortable, looked like it did in the photos. Very functional with three single beds (two you could put together) and a table and chairs. Nice little kitchenette and a spacious bathroom. The checkin was easy and checkout very simple. I felt safe. Axel was friendly and warm and took the time to tell me whatever I needed to know, and make suggestions for the area.
