Rainer was at the flat when I arrived and allowed me to check in early, as well as leaving some chocolate which was a nice touch. He is a very friendly and knowledgeable host who provided me with an annotated map with all the good spots in the city.
The flat was notably spotlessly clean and had everything you need for cooking, as well as an iron and washing machine. The bed was very comfortable and heating was easy to use.
Overall, you have to say that the toilet and bathroom are somewhat dated, with brown tiling and the boiler over the bath, but again, totally clean, with all towels, toothpaste and soaps provided.
It is also worth noting that there was a neighbour who would bang on the wall for myself and my partner to be quiet. This was at only half 10 on a Saturday night, and we were not playing music.
The location is excellent, only 10 minutes from a station, or there is a tram stop minutes away. To walk to the centre of town takes about 25 minutes.
Overall very impressed, and thanks to Rainer.
