I stayed for six nights at Rosemarie's place and enjoyed it very much! Quick list of pros/cons:

Cons: There happened to be a large-scale construction project going on right next door, and the workers would begin drilling/hammering/operating machinery at 6:30AM every day. Given that I was here for work, this was very inconvenient and extremely stressful. I don't blame Rosemarie at all since there is nothing she can do about it, but I do think guests need to be forewarned for as long as the project is going on.

Pros: The keyless entry was great and convenient, and there was also a key available to use just in case. The apartment is HUGE with lots of space and could easily fit a whole family. The place was clean, lovely, and lots of kitchenware available for use. The location was fantastic, right near the UBahn and walking distance to great restaurants and bakeries.

Overall a good experience, especially once the construction project is over!
