The selling point here is that all rooms have a really nice view as well as balconies. Don Biyu also has a very friendly and helpful staff and offers a decent breakfast. Diner options are good as well. We enjoyed our stay here.
However, we find Don Biyu overpriced. We payed almost 50 euros per night. For that price we got a really basic room. It smelled a bit damp and looked worn down (stains on the walls and floors) just like the premises.
The room also wasn't entirely clean: when we arrived we found a lot of ash and cigarette butts on the balcony. The next day this was cleaned, however.
We've been to other small scale hotels on Bali and for the same price we got so much more in terms of facilities, decoration, furniture, cleanliness and customer service.
We don't mind staying in basic hotels, if the price is right. We could have found better value for money in Munduk. That's why we would not stay at Don Biyu again, even though we enjoyed our stay.
