What sort of accommodation can I expect in Kathmandu and during the trek?

We use from 4-5 star hotels in Kathmandu, Pokhara, Chitwan and major tour places with breakfast included. Along the trekking routes, we uses upscale deluxe lodge, wherever available or  slightly lower categories if not,  but clean with attached bathroom. It is a good idea always to have your sleeping equipment. The lodges in trekking routes usually provide single and double rooms. At times when possible, dining will be around a bonfire.
