Dushanbe has some respectable midrange business hotels but is particularly short on good, cheap accommodation. In contrast the Pamir, Fan and Zerafshan mountain regions have a good network of homestays but nothing upmarket. Indeed most places have outdoor toilets and few have hot showers. Some, but not all, have signs; community tourism outfits PECTA, META, ZTDA and tourist information offices have lists of signed-up homestay families. In places where there's no formal system, it is appropriate to offer around US$10 to US$15 per person if you are hosted. Possibly you'll need to put the money in an envelope to avoid polite refusals. Very few hosts speak English, but most understand Russian.
