How far is the nearest supermarket? My mum is lactose-intolerant so she'll need to buy lactose-free milk. Does anyone know the availability of lactose-fee milk in Amsterdam? Otherwise she can settle for soya milk in the hotels. Thanks in advance.
There is a great market quite close, as well as a couple of 'health food' stores. I think you will very easily find what you want. You can call the front desk for the name of a couple of stores and call the stores. The folks at the desk were incredibly helpful.
