We stayed at Stefan's place for nine nights on July. 5/5, everything was exactly as stated in the advertisement. Stefan is a great, relaxed host with good knowledge of local surroundings, such as public transport, museums and other sightseeings.
The kitchen is well equipped for cooking. We made our dinners there several times during the visit.
The beds were good to sleep in. Toilets and shower were clean and worked as usual.
Location of the apartment is good - ~1.5km to west for Hirscgarten - ~3.5km to east for city center - ~2.5km to south for deutsche museum. It's also ~650m from nearest S-bahn station.
I can easily recommend Stefan's place for other travelers.
