Casper's apartment is really great, and has everything you could possibly need for a stay in Antwerp. Unlike many Airbnbs he provides lots of glasses/cups/plates/cutlery for the number of guests, and all the amenities you need to cook for yourself.
The rooms are light, spacious and well thought out with plenty of room/space for guests to unpack and make themselves at home. The bed is a full, proper king-size bed, in a bedroom that has lovely light in the daylight, and proper black out curtains for sleeping. As other reviews have mentioned, despite the fact that the apartment is in the centre of the city the bedroom being at the back of the building means it is completely silent for sleeping.
The location of the apartment could not be better: easy walking distance to all the tourist sites, plenty of bars/restaurants on the street, a bakery a few doors away and a supermarket a few doors away the other direction. The park for walking our dog was about 6 minutes walk away.
Casper was a really great host, very accommodating. He organised a super-early check in for us, sent us details of where we could walk our dog, park our car and was generally really helpful with all our questions/queries. Without a doubt this is where we will stay when we are next in Antwerp - highly recommend!
