Michael is a great host that helps you with anything you need. I stayed at his house for three weeks and he was always nice and helpful. He fixed the heater of my room, showed me a laundry shop, and even gave me one of his bicycles to use. The room itself has a big comfortable bed, and next to it is a big kitchen which is great if you wanna cook regularly. As it is a shared place with around 4 others, it can get a bit messy and dirty in bathroom and kitchen, but it gets cleaned once a week. I personally didn't mind and enjoyed my stay in Antwerp. For sightseeing it might not be perfectly located though, as it takes a while to get to the center without bike or car.
