Things in Bali are not usually clean, even in more expensive hotels. My room at tune hotel was quite clean except for the sheets, but I never found a clean sheet in Bali anyway. For 10 dolars per night, the hotel is very pleasing. Comfortable bed, decent shower. If you just want a place to sleep and spend most of your time doing the stuff tourists do, then Tune Hotel is a nice choice. But if I were travelling around with my girlfriend in some romantic vacation, I'd look somewhere else. But I say again, for 10 dolars per night, I believe you won't find anything better. Heck, it is even better than hotels where I paid around 50 per night.
The downside is that you have to pay for WiFi... but you would do better buying a simcard with 3g. In most hotels I stayed the Wifi was pretty bad; I didn't tried Tune's WiFi but I have no reason to believe it would be any different.
