My boyfriend and I stayed with Beate for two nights during our interrailing trip around Europe. Unfortunately we were unable to meet Beate due to our clashing schedules, but she was able to efficiently exchange keys and left us nice notes on the fridge each morning.
The location of the appartment was good - a bit our of the centre but easily connected by both tram and metro lines. The room was clean and comfortable and there were a selection of guide leaflets available which was very helpful. She even left a little chocolate for us on arrival!
A very enjoyable stay :)
