We really enjoyed our stay at Amano Home apartment hotel. The apartment was very clean. The style is minimalist and maybe a tad bit "white", but it creates a cosy atmosphere, in particular the futon-style bed. All the basic facilities (fridge, microwave, cutlery, plates and glasses, coffee/tea) you want are easily accessible and stowed away in cube-style cupboards. The bathroom has a tub and (good) shower (and a huge class window facing the room, thankfully it could be closed with slat curtains). The hotel is very central in "Mitte" and various nice areas can easily be reached by foot (Hackesche Höfe, Alexanderplatz, Prenzlauer-Berg, Wasserturm). Lots of good restaurants and shopping option close by + a large variety of "Späties", kiosks to buy snacks, drinks and basic groceries (good for late-night shopping).
There was a bit of a misunderstanding during our (late) check-in where, at first, the reception (which we had to communicate with through a phone in the lobby and which is based at another hotel) hadn't realised that our booking came via Airbnb and didn't see a verified credit card, but this was resolved promptly and friendly. Also, inhouse internet was not accessible anymore after 3 days (some problem with the log-in server). This being Germany with its infamously bad digitalisation, be prepared for some hickups with these issues. All in all a very pleasant experience which can be recommended.
