My partner and I had a great stay for one week at MiniLoft. Very easy check-in process, quick and friendly communication, very comfortable bed, central location, and minimal/modern design in a newly constructed building. My only comment is the construction noises outside the building (as of 09/08/19), so if you're sensitive to noise I would recommend bringing ear plugs. Regardless, we felt it was a minor issue as the apartment itself made up for it and we spent most of ours day experiencing Berlin!
