Tent guesthouses are available at EBC (Everest Base Camp). They are rectangular, black tents made of Yak wool with a few beds (2-5 beds). All beds are covered with Tibetan carpets and can be used as bench seating during the day. There are also small tables inside. In the middle, there is a Tibetan-style stove that keeps the whole tent warm by burning cow dung and wooden blocks. Solar cells are the only source of electricity and it is very hard to find a place to charge your electronic devices. At Namtso Tashi Do Peninsula, there are both tent guesthouses and cardboard guesthouses are available for your option, so far both are clean but cardboard guesthouse is recommended as it is much silent at the windy night.
