I highly recommend Claudia's apartment if you want a place that is centrally located but in a quiet, residential neighborhood. The check-in/check-out process went very smoothly and was "contactless". The bed was quite comfortable and the linens were fresh. Having a washer/dryer machine was great! Lots of choices on the flat screen tv. The kitchen was very well-stocked. You have to be able to do stairs because the apartment is on the third floor and there is no lift. Public transportation is just a half block away and there are lots of grocery stores with organic foods and delicious bakery items within easy walking distance. On my next trip to Berlin, I would like to stay at Claudia's again.
