Michael was a super guest, extremely reactive and polite, we didnt have any problems with our check in, the apartment, and the whole experience. All the instructions were given in full detail, so that we didnt have any difficulty.
The apartment is a 20 minute walk from the central station, and on a 1st floor with no elevator - for us it wasnt a problem at all, but to someone with mobility issues it might be a good to know that there are two sets of stairs.
Theres a market right below the apartment, and all the main attractions of the city are reachable on foot.
Very nice place to stay if you want to visit Antwerp!
