Our family of 4, with a 4 year old and 22 month old, stayed at Anna and Michael's place for 2 weeks.
Pros
* Location is very good for young families with a really nice playground only 5 minutes walk away and others close by, also lots of casual, moderately priced restaurants within 10 minutes walk of apartment.
* Our kids really enjoyed the toys left for them to play with. We were also happy with the high chair and crib.
* Anna and Michael were quite responsive to any questions.
Cons
* Wifi is really bad, practically only good for checking email and light browsing periodically as its both slow and spotty. We learned the hosts share their internet with a neighbor, and the modem/router is in the neighbor's apartment. A wifi repeater is in the Airbnb apartment, and repeaters are known to not be very effective. While spotty wifi may be an issue throughout Germany as the host explained to us, fact is if the modem/router was in the apartment and the connection was private, the wifi would be better than its current state.
* Kitchen did not have a microwave or toaster. While the host explained there should be a toaster, we checked where she instructed us to look, as well as throughout the rest of the apartment and it was no where to be found. Perhaps someone took it? Living without a toaster was fine, but no microwave with two young kids got old real quick.
* Sofa bed does not pull out into a double bed, but rather breaks apart into two singles, with no way to attach the two to make a double/queen.
* We were not provided any drawers/shelves to store our clothes. All drawers, shelves/spaces where stuffed with linens, so we had to store our clothes on top of the bedroom dresser.
