As above really...

Going out to Amsterdam for 4 days at the end of the month and whilst my friends are taking a day trip to Ajax Stadium, I'd like to get an hour or 2 on the mats in the afternoon with my cousin.

Can anybody recommend a tourist friendly gym near to Wertheim Park/Botanical Garden in the Plantage area?

If no open mat, a class would be fine or even a tourist friendly kickboxing gym?

Thanks in advance,

Ste
