We are currently in Sanur and absolutely love it! It's nice and relaxed, not too busy, but there are plenty of bars/restaurants to choose from. This being our first trip we were not sure what to expect, but would definitely come here again.
We also decided to book our taxi man from the airport to take us on a tour of the island. He was fantastic and made suggestions as to where we could go, but left the choice up to us, if we said no then that was that, no pressure at all...he even saved us money by taking us to areas where we could view the rice terraces for free instead of paying an entrance fee. We are not really ones for doing all the tourist hotspots, preferring to make our own way around, but I can say the Monkey Forest was fantastic fun (but very busy), plenty of monkeys to see and very tame. Be warned though, they do like to jump onto your back and lie on your shoulders! Also had a fantastic lunch at the rice fields in Ubud, again one for the tourists but the view was spectacular., with a lovely cooling breeze blowing in from the fields. We were lucky to virtually have the restaurant to ourselves and left just as the crowds began to arrive (we had an early lunch at 11:30, it was filling up by 12:30).
Only downside is the fact that my wife has been bitten by the mosquitoes. No matter where we go or the amount of sprays, creams and coils we use, they always get her...and she reacts badly to them. Currently she has two bites that have swollen up, one is about the size of an orange. She is now sat on the bed covered in wet cloths to try and stop the itching. Luckily the chemists here seem very knowledgable and have given her some antihistamine tablets!
