I stayed at Jonadda during my first visit to Chiang Mai in 2007.
It had since has my custom 3 times and I recommend it to people going to Chiang Mai.
Panadda has always been friendly and helpful - giving advice on how and where to go as well as booking things for a good price.
I've stayed in pretty much every type of room they've got & they're ALL clean & comfortable.
The staff are all excellent. Really can't fault this place.
