Hi Ludwig,
Thank you for hosting us in these few days, we were enjoyed to have a chat with you and you're really funny guy with the optimistic attitude.
Hope you will keep on going with this friendly and welcoming atmosphere in running your business. May you to have a bigger success in the future.
Here are some suggestions in overall of our stay, it would be more nice if there are some daily supplies provided for your guest, e.g the basic coffee and tea, tissue paper, hand towel, cooking materials, hair dryer etc. But also, the bed can be more softer ;)
Anyway, these just our personal opinions. We did still enjoy our stay in your house, your radiator is warm and the shower is hot enough.
Location is great.
Cheers,
Michal and Sandy
