First of all: If you expect just a tiny little bit of hospitality, this isn't for you. Nobody will care about you as a guest.
Also, don't consider any of the apartments of Chaussee36 when you're on a business trip, because they're all connected to the same Wifi and lack bandwidth.
I got there on a Saturday, and realized that the bandwidth wouldn't be enough to run my remote meetings (with video) the subsequent week, and due to COVID I had no other option than working from the apartment. I raised my concerns, but nobody heard me or got back to me to fix the problem or at least explore solutions. My whole Monday got messed up, I missed the whole day of meetings which caused me a lot of trouble. The host who had ignored all my messages only reacted when I got desperate, but still didn't come up with any solution.
It's such a shame how poorly managed these beautiful and gorgeous apartments are. I didn't have any special wishes, so in order to keep me satisfied I only needed a very basic service and a basic level of respect. However, it felt as if nobody really cared at all.
