I am a business traveller and use Airbnb from time to time. I was comfortable at Rosina's apartment which was well located near to transport links in Berlin. The apt was situated in a nice modern building and quiet neighbourhood. The room was a nice generous size, and clean and tidy. I didn't use the kitchen at all but it looked perfectly ok, the bathroom was small but no problems. Rosina and her family were very welcoming when I arrived, due to my work schedule I didn't see them again. Overall I would recommend for other travellers. I didn't see any local shops very close by but that didn't impact me.
