Gerhard is amazing! Before arrival he sent very detailed instructions message with all the information you need. He even offers late check-out if apartment is free on following day and you can use parking place after check-out. Apartment is very different to what I am used to, but we enjoyed our stay a lot. Apartment is a bit far from subway to my likening (10-12 minutes walk). I was afraid apartment would be cold inside, but it was fine.
