You will spend three nights in a well located hotel in Beijing and five nights in simple guesthouses whilst on trek.  Please be aware that accommodation options are limited on trek and the guesthouses offer simple mountain accommodation. Rooms are twin share and have en suite bathrooms. The bathrooms are equipped with Western toilets and there is hot water (although this can be erratic and somewhat unreliable). It can get cold in the mountains and the guesthouses have no central heating but sleeping bags are not required as blankets are provided. There are usually electric heaters available upon request. There is electricity but there can occasionally be power cuts so a torch will come in handy.
