I had a great stay at Johannes house!
Loved that it wasn’t some big landlord, but really just a guy renting his house traveling - as it should be :) The house felt really authentic with travel photos around. Johannes was communicative and clear, the location was great (a few metro stops away from the center) and calm. Picking up the keys was really easy too.
Just the bathroom is really tiny, but for a few days to explore the city it was fine. :)
