Good lodging is always essential during your trekking period. Considering those, we will manage a teahouse/lodge accommodation on your trek.
You can divide rooms for two people, one sharable squat style toilet. Toilets are on the outside of the house. Most of the teahouses will provide you with a blanket.
But carrying a sleeping bag is advisable because the rooms have no heater. Thus sleeping bags will help you in such a case.
Some lodges may provide hot water, but you have to pay extra charges for its use.
