Just curious... have you checked out these places already? They have very different things to offer in terms of size, view, location, amenities etc. If renting anywhere around West Bay/Dafna area (which includes the zigzag), the one thing you need to watch out for is the additional charge for the aircon i.e. Qatar cool. In some cases, the landlord takes care of it. More often, they don't. Depending on the size of the apartment, I must warn you it is not a nominal charge.
