Overall, the apartment worked fairly well for my group (3 adults + 3 kids) - excellent location with plenty of stuff very close (including the Isar for swimming, which my kids loved), problem-free check-in and although we had a couple of minor problems with the refrigerator and WIFI the first day, Flo's team were very responsive, friendly and helpful.
The things that weren't optimal (for us, at least) were the kitchen which just wasn't really properly equipped or useable, the bedding (the pillows in particular were very poor quality and uncomfortable), and the lack of washing / drying facilities (or a drying rack) - the advert on AirBnB did make it clear that these were not available in the apartment, but I think that these are something that - given the overall cost of the apartment - could reasonably be expected to be provided.
