We spent several days at Crest Safari Lodge before and after a camping safari. For the price range, the hotel provides excellent accommodations: rooms are clean, hot water is available (though pressure can be low in the mornings), breakfast is filling, with an omelette, scrambled eggs and pancake station, as well as cooked foods and breads, fruit etc., and provides healthful options. Front desk and dining room staff are very friendly and extremely accommodating.
Depending on where guests are placed, some rooms can be a bit noisy from roosters crowing in the morning, or (in the case of the rooms at the top of the stairs leading from the lobby) from echoing noise from the reception and dining room area.
The hotel is a little far from downtown and the access road is a narrow, ungraded dirt road, but shuttle service is readily available at the hotel.
Overall, good value for money and if in Arusha, we would stay again. Recommended to fellow travelers.
