My partner and I recently stayed at Aria Villas for 4 nights and loved it. Loved the privacy of our own pool just for us and the outdoor stone bath and shower! Breakfast was good - we ate in the restaurant and also had it delivered one morning to our villa where we ate beside our private pool. Felt very spoilt and the service was impeccable! Everyone was so friendly and welcoming, made our stay complete.
Location was ok, 10 minute walk to potato head and 5 minute walk to Sarong and Biku (all places worth visiting). Less then a 10 minute drive by taxi (equivalent to $1 aud) to Seminyak Square, and a 20 - 30 minute walk to any sort of good swimming area along Seminyak beach.
Only couple minor things (which wouldn't put me off from staying again) were: the hot water running out if having two showers in a row; and the rooster crowing at 6am every
morning. But overall loved our stay and especially the wonderful staff. Must add that we got a special deal over the Internet with a private single bedroom pool villa for $200 a night (I believe this villa is normally double that price).
Would definately recommend if you don't mind not being right on the beach and love the privacy and serenity of your own pool and villa.
