Bali is famous for its beaches. Sanur is one of the beautiful white sandy beach in Bali. There are resorts that has their private beach. If you stay in a place with no private beach access, you can go to Sanur and enjoy you free time there. Actually, for myself, I rather stay in Sanur than Kuta, Bali. Kuta has its perk being the closest beach to Airport, clubs, restaurants etc. Sanur has a quiet and relaxed ambience.
