We stayed in the Marc's place one week and we really enjoyed beautiful city of Antwerp.
The apartment is close to the main station, about 10 minutes walk and the neighbourhood is super quite and calm.
There is enough space for two or three people, kitchen has some pots and pans, the bathroom is big and bed is very comfortable.
The historical centre is about 30 minutes walk or you can rent a bike very close to the apartment.
The local stores are over the corner and big supermarket is very close too.
