The apartment was spacious and very well located, in a pleasant street close to a tram line and a Metro station.
There is a good café opposite and supermarkets and shops are nearby.
The apartment was exactly as it appeared in the photos. It was sparsely but adequately furnished and equipped and was very quiet, due to double-glazed windows (noise from the restaurant could have been a problem). The bed was comfortable.
There were no issues with gaining access and Klaus, the host, was very helpful. A nice surprise was a cleaning service and a change of bedclothes and towels mid-stay (we were there for one week). We really enjoyed our visit to Berlin and I'd certainly recommend this place.
