My friend stayed in the AirBnB and she says the following:
"I spent just over two months in this apartment and I must say it was one of the best AirBnBs I ever stayed in. The building is an amazing old factory with high historical ceilings - and with a view towards the tv tower!
The apartment itself is spacious and very well equipped - everything you need for everyday life is provided - you only need to come with your clothes :)
The area is also very nice with sufficient restaurants, supermarkets, bakeries, and bars just around the corner. Public transport is in front of the door and takes you easily around the city.
Contact with Armin was really friendly, quick and smooth - as it should be.
Conclusion: a great host, a great place in a great area - I would definitely stay here again!"
