The flat and rooms were clean and tidy, but I could not access the internet. Jorg was unable to help although he put me through to his neighbour who runs the wifi. The problem could not be resolved over the telephone and I had no internet access during my 4 day stay. It remains unclear if the problem was a setting on my new laptop or an older version wifi.
Another guest offered his computer so I was able to quickly check messages. Jorg could have offered similar access, but I did not feel comfortable enough to ask. Jorg had asked me to pay a Berlin tax when I arrived, and I declined to do so because it was not disclosed through AirBnB. Jorg did not press the issue.
Jorg seemed a correct, but not effusive, host. I would not hesitate to stay there again and would recommend the place to others.
