Sebastian is a delightful person and I strongly recommend his Airbnb to anyone looking for clean, quiet space. Right from the start the level of communication was responsive and cheery. When I couldn't quite find the entrance and phoned him - it is actually very easy to find! - he came down and carried my suitcase upstairs. We only met for about half an hour but during my stay he texted me to check that all was OK. The double room is plain and simple and oh joy of joys it has a window that opens to fresh air and is away from street noise. Bathroom was clean up modern and there were supplies if'd you'd forgotten your own. An added advantage was that the bedrooms are on a top floor with their own door out of the flat which worked well for me as I didn't want to invade his personal space.
Lots of restaurants & coffee shops are near by.
