I stayed at the hemp hotel from 29/3/13 - 3/4/13
"A lovely little place" probably best sums up the hemp hotel (I know I'm not the first reviewer to say that, and it's easy to see why) the staff at the hotel are very friendly, welcoming and helpful. I stayed as a solo traveller (first time solo holiday and first time to Amsterdam!) and they couldn't of made my stay any more comfortable. Breakfast is nice too.
The rooms are themed and fairly basic but nonetheless comfortable and a good place to get your head down after a long day.
Probably worth mentioning that although the hemp hotel doesn't sell weed they do have an amazing bar which is one of the very few places in Amsterdam where you can drink alcohol and smoke weed (bring your own obviously) wonderful chilled atmosphere and lovely people. Going back in August, can't wait! :)
