Karin's place is just gorgeous! It is perfectly clean and very well equipped. The bed was comfy and had high-quality linen. You can easily reach the city centre on foot. We can recommend "Kingfisher" for breakfast (just a 5 min walk from the studio; thanks Karin for the great tip!) and if you like burgers, "Bunsen" is really the place to go!
I recommend bringing ear plugs with you as the windows don't fully insulate the studio from the traffic noise (plus there's an mechanic timer for water heating near the bathroom that's constantly ticking). It really depends on how noise-sensitive you are, my boyfriend didn't bother at all but I definitely needed ear plugs ;)
All in all we can highly recommend the studio and would definitely come back!
