Uma Dawa was one of my favorite hotels of my 15+ day stay across 5 countries. What I loved about this location was how it felt like walking inside a temple with beautiful gardens, statues, birds and a magnificent swimming pool in the hotel grounds.
The room itself was very nice- reasonably large sized, spacious bathroom with all facilities I needed- fridge, AC, TV. The front-desk guy (whose name is Agung) was very helpful- he helped me with carrying suitcases, arranging scooter for me with GPS holder, giving travel/ laundry suggestions, and even helping me with Grab when I didn't like the price quoted for going to Seminyak (although they do offer that service too). There was a young boy who works there, who was very helpful who helped me by coming to my room when I struggled with locking door, turning AC on etc. and served lunch to the room.
The location itself isn't super central- Ubud Palace was ~10 minute drive on scooter, rice terrace was ~20 minute, Monkey Sanctuary ~15. So if you can't drive a scooter/ don't walk to take Grab, it might be inconvenient. One of the major complaints I would say is Google Maps confuses destination and says "you have arrived" 1-2 minutes away, and it is not very clear especially in the dark where precisely it was.
Overall this is a bargain. Amazing grounds, cheap price, beautiful rooms.
