Jan's appartment is an amazing place to stay in Antwerpen, because is an historical place, lovely decorated, very bright and pacefuly.
The appartment is very good located, walking distance to many attractions and beside restaurants, supermarkets or coffeshop. Also, you have everything you need in your day-to-day in the appartment, if you need something special Jan will provide it without any problem.
I highly recommed stay here, you will not regret. If you have any doubt ask to Jan.
