Stayed at Circle on Cavill Ave for 5 nights on level 12 which had amazing views of the ocean, and of the shopping areas on Cavill Ave etc.
The apartment was beautiful, very modern and clean, with everything you needed and more.
The pools, bbq area, playground and viewing deck were amazing, and my husband liked the spacious gym.
About the only possible downside was the noise of all the entertainment in the area, but even that was only mainly Fri. and Sat. night.
We had booked the room privately so everything was arranged without dealing with reception etc., but that was not a problem at all as a large number of apartments are leased this way.
So a great place to stay, forget the car, (oh and the kids loved their big spa bath).
