I just got back from a trip to Chiang Rai, we stayed at the Amarin Resort which is near the river and east side of the city.
Nice comfortable place, very quiet and the breakfast was very passable.
This was our room.
It even had a bog
Out side there is open space with well tended gardens.
Terrace outside room overlooking the garden
