We had a nice stay at Christoph’s air bnb! It is in a lovely quiet area within a short walk to the metro. Christoph provided us with links of thinks to do and places to see and eat. He was also flexible with our check-in as we were running behind due to car trouble.
I will note that this is a room inside Christoph’s house and the bathroom is not attached to the bedroom, so you do have to go into a public space to get to the bathroom. Fortunately, it still felt pretty private.
