The description is accurate, the communication with Matthias was simple and easy, he provided all the instructions for our arrival. We only saw each other once, but this was enough for all we needed.
The place is comfortable and clean, there is no breakfast included (which is written in the description), but there are towels, linen, hair dryer, all kitchen facilities etc. We were 3 people (myself and my parents) and Matthias's place was big enough for us.
