Karsten’s place was okay/nice. First, the good: the apartment itself was very nice. Big, modern, and clean. The location was very close to Old Town. Just about 5-10 minutes walk.
There were quite a few negatives. I think we underestimated the heat. As Texans, we can handle hot. However, as noted in the description, the apartment does not have an AC unit. It does have a small fan, but I do not think the small fan matches the size of the apartment. Also, the windows, though big, only open partially. This prevented a breeze from truly cooling the apartment. In late-July, this was needed! The neighborhood was very close to Old Town, but the neighbors themselves were very noisy. Lots of talking and laughing from outside the windows until 3 AM. In the morning, we’re woken up with loud music too...
Karsten’s response was a bit slow. We stay in AirB&B’s often, and hosts typically say hello once booked, and then follow up with you about a week before your trip with logistical information on how to get in, etc... We did not hear from Karsten until our train from Zurich to Munich was on its way (even after sending him a couple of messages a few days before). As a planner, this made me nervous! Maybe this was because his buddy was taking care of us this time, however, clearer communication definitely could improve.
For the price, it’s not bad. However, some improvements could make it better.
