Something to keep in mind (that I forgot) is that you want to try sending your questions through airbnb as much as possible since, from what I understand, while the place belongs to Angelika, Carsten is the one actually helping to handle the airbnb. On that note, they(?) were responsive to all of my questions and gave me great advice when I asked about parking (e.g. i can't park a u-haul on a residential street). It's a good idea though to give them at least 24 hours to get back to you, which I failed to do so I got my advice a little later than I wanted.
I had a bit more unique situation this time in that I was moving to New York for work and was staying at the airbnb as a midpoint while I looked for housing. That being the case I had quite a lot of luggage...This place was great in that it was located on the lower level so I only had to navigate a small step, and you get the whole unit and so we had plenty of space to leave our boxes in the living room.
For the most part everything was good about this airbnb, but for a few minor details: they don't provide paper towels, there was a handful of ants that would appear on the kitchen counter every day, there was some leftover food (like eggs past their best by date) from previous tenants left in the fridge, and the internet often disconnected every few minutes such that it was more reliable to just hotspot my phone.
