So far this is the best place I've found in Ubud for Digital Nomads. Not only do they have AirCon in every room but also a fan, 60/60 BIZNet fiber internet, hot water kettle, but also a desk and chair which is required if you work on your laptop all day.
Here is the information: Search for House Name: MANGGIS SARI GUESTHOUSE
