We have used Hotel Tojikiston, Dushanbe many times. The rooms are comfortable and the housekeeping staff are extremely helpful. The breakfast is OK (by local standards) but for the rest of the day the hotel restaurant is absolutely useless. However, the location is excellent with Rudaki park, a good Indian restaurant and several good cafes within walking distance. This is not the Serena or the Sheraton but its quirkiness is somewhat endearing - and it always has vacancies!
