Florian and Christine are wonderful hosts! They were very welcoming, and whenever we had a question or needed help, they were available to help us immediately. They live in the same building, which makes communication even easier. They gave us a welcome gift and a parting gift, which was very thoughtful!
The house is very well equipped, especially in the kitchen. You have pretty much everything you might need: iron, ironing board, hairdryer, plastic garbage bags, coffee machine pods, tupperware, different sorts of glasses and plates, all sorts of cleaning supplies, city guides, umbrella, etc etc the list goes on... On the last day we asked to borrow their scales (to weigh our luggage) and they happily lent it to us.
The tram/train stop and the supermarket is only 200 m away so it's very conveniently located. The train tracks go in front of the living room windows so expect to see and hear trains passing by (you get used to it quickly).
We stayed there for 2.5 months and generally had a very good time there. The most significant issue we had was that the fridge is small and does not have a freezer. We managed to get by without a freezer, and from my research I've seen that most houses on airbnb have small fridges, but I'm writing this so that future guests are informed, in case you want to keep ice cream or frozen food in the house. The other thing that bothered us was that in the summer heat we kept the windows open, and flies/insects/spiders kept coming into the house. However when we pointed this out to Florian he offered to install a fly net and provide us with a mobile air conditioner.
Overall it was a very pleasant experience and I would recommend their place.
