It was a great stay at Hannes' house. You do feel like home away from home. The bed was great for one person, the room was plenty with a couch and working table. Hannes and Leo (his son) were lovely to talk to. In the morning, Hannes even went out of his way to prepare an awesome breakfast and helped me with the transportation. We had a great chat and I learned a lot from him. The location was very convenient to the airport, although it might be a bit far from the city centre but it was manageable by S-bahn and bus. Will stay here again next time!
