Nice place!
We stayed at Designer Loft for 4 days. It was clean and equipped with everything that we needed (iron, hair dryer, big tv with netflix).
We had no problems with communications, check-in and check-out. Sascha was very friendly!
Bed was quite comfortable!
The location is a bit far away from city bikes sharing. But it is near the zoo and the technical museum. The windows overlook quite a busy street which can be pretty loud at night with opened windows. But it has jalousie and blurring, which helps a lot.
We definitely recommend the place!
