Kem is brilliant at orgainsing everything and not at all pushy on selling tours (everyone in Chiang mai wants to sell you tours to get commissions - hotels, guesthouses, taxi drivers). A great source of what you should pay to go places, we went off the beaten track to a town a few hours from Chiang Mai and he planned out the route for me.
Rooms are fine, we added a third bed to a double which was just a thin mattress on the floor, but nice place overall. The hotel is around a ten-fifteen minute walk to the old town, it is on a street very near to the night market.
