To be honest I went with POP because I resemble a bird in that I'm attracted to colorful, shiny things. POP doesn't disappoint, as it positively drips with cheer. Don't let this deter you, it's just a wildly colorful and fun place. The hotel itself is open 24 hours a day and is beautiful and shiny, the public spaces kept spotless by the friendly staff. The rooms themselves are well-designed, efficient spaces. Don't come expecting vast rooms and Victorian appointments, however. Each room has a very comfortable full-sized bed, air-conditioner, wifi access, flat-screen TV, safe, bench sofa, and a miraculous marvel of engineering I'll refer to as the bathroom bullet that combines a toilet with the shower (they are separate inside, you won't be standing on the toilet to take a shower) in a well sized, enclosed bathroom space in your room. There are a number of other nice touches, such as conveniently located on/off switches, LED reading lights, and a universal outlet (power point) just in case you forgot an adapter.
POP is located in Denpasar, about ten minutes by taxi from the Denpasar airport and Kuta. The neighborhood though not spotless, is vibrant, lively, and very local. The street food is excellent and the people friendly. There are always taxis to catch so transportation is never an issue.
I'd recommend POP to the young, the hip, or the frugal (who want a lot for their money). I am a very happy customer and intend to return the next time I'm in Bali.
