W Seminyak have better location compare to Ritz-Carlton Bali (Nusa Dua)

W villas is more secluded compare to RC villas as W villas are on separate area from the hotels main building but expect zero view from those villas.
Woobar did have nice location to watch sunset (or just watch at one of many of Wet Deck pool cabanas)

Nusa Dua (RC) area was not really close to any interesting area as Nusa Dua is more like a gated complex full of resorts.
While Seminyak area are closer to Canggu and Kuta area.
There are a lot of nice eateries within walking distance of W Seminyak

But traffic would be quite bad near W though.
