I underestimated the travelling time so we didn't know we were about to spent the whole day on the road. Jumped on the bus to Bajawa, after a lot of confusion and bargaining again, you never know what the real price was is, it turns out the ride took 12hr. Lots of stops on the road, picking-up/letting down people, grain bags, live stock, mechanical spare parts and others. We arrived to Bayawa by dusk and checked in at Silverin Hotel, which has a nice view of the hills especially by sunrise and is decently run. We were very tired and went straight down to sleep.
It would have been a better idea to break the road trip from Maumere to Bajawa in two, maybe staying over in Ende makes it more manageable.
