Orchids is more expensive than many guesthouses in Chiang Rai, but you can see why when you get there. Very clean rooms, nice bathroom with hot shower, AC with remote, cable TV with remote, fan, and complimentary water bottles, toilet paper and soap. The staff is very friendly and helpful. They will set up all kinds of excursions for you, they rent motorbikes, and have free coffee, tea, cocoa and fruit in reception. There is also a big fridge in reception where you can store food and purchase cold drinks. And they have a masseuse that will come to your room. 300B for a 2-hour Thai massage.
The location is close to the main strip, the night market and the 24-hour market, but away from the noise. The street that it's on has many cafes and bars that are a fraction of the price of the ones on the main road.
