We stayed at Aria for 5 nights in October and were fairly happy with our stay. The villa itself is nice, clean and spacious with typical hotel-decor and provides complete privacy. The only thing that I questioned about the villa is the mosquitonet which doesn't have a roof and therefore completely has no purpose.
The staff is very friendly but, except for receptionstaff, feel a bit confused and not really on top of everything. Housekeeping didn't come until late in the afternoon why we had to call for it to avoid being interrupted during afternoon nap or having a bath before leaving for dinner. To be fair, they did a good job when getting there.
Breakfast is average although we didn't understand why the buffet changed after two days resulting in fewer choices. The rest of the food we had was also average, including the candle light dinner during which we almost fell asleep waiting between courses.
Aria deserves a gold star for being the only accommodation on our trip who sent an email prior to our arrival welcoming us and offering to arrange free airporttransfer and express arrival (a perfect service well worth the extra $25 per person). I should add that the others were 5 star accommodations. Overall the receptionstaff were always not only friendly but also fulfilled our needs efficiently. I would also like to mention one of the guards in the back (a tall guy) who was kind enough to watch over our shoulders when arriving with taxi at night so we wouldn't be tricked by the driver. What a nice touch!
Aria definitively has potential with a little more experienced personnel and as soon as the madness of the constructions next door are finished. The peaceful atmosphere that Aria aims for clearly can't happen until the drilling noise stops.
