Hi,
In Reem Island, I live in Gate Tower. The outdoor facilities are great, very green, with 3 pools, play areas, tennis court, basket, squash, 4 gym, a movie theater... I like this place. The only big bad point for me is you can not open the windows. There is an indoor bridge to go to Sun & Sky Towers where there is a supermarket and a food court, hairdresser, salon. Sun & Sky towers are good apartments and facilities too. The outdoors one are just without trees or grass. Not far from there, there are Beach Towers with great balconies and a small grocery shop but a tiny swimming pole.
I do not recommand Mangrove apartments (just in front of Sky Towers), the facilities are bad and the apartment I visited as well.
An other good point is that in front of Sun&Sky, there is often a lot of taxi and 2 bus lines begin there.
Good Luck for your search!
