So many choices with that budget. Which area do you want to live in, once you know or tell us then it will be easier to guide you. I believe that most of the service apartments are in West Bay area. You have Sommerset, Beverly Hills Tower, Al Maha Towers, Asas Twin Towers plus many more.

Beverly Hills Tower has an outdoor adult pool plus a kiddies pool as well as an indoor play area. There is also a gym and soon to be opened spa and mini market.

Good luck
