Great location in walking distance to Mitte and Rochus station, close to many restaurants, Hundertwasser iconic building and other attractions. The apartment is huge and can easily accommodate a large group of people, a rare find in this area. Really worth the price. The facilities are mostly good, with a separate main, large and well equipped kitchen, espresso machines and smaller kitchens in some rooms. The bathrooms are good, yet two of them were still under renovation when we stayed. It didn't look very attractive, but that didn't bother much. The lack of AC also didn't bother us even when the temperatures went rocket high to 36°C/97°F. Being well isolated, and keeping the windows closed at day and opened during the night, we didn't feel the lack of AC disturbing in any way. The only point to improve was the communication with the hosts. Their response time was sometimes slow, for example when we had an issue with the water heater or a stuck window, which were eventually resolved.
