The Marriott ones are quite nice.
When our house was being finished we lived in the villas at the Yacht Club.
DHs work organised everything for us but I'm sure they were through the club itself, not through the Hyatt, as any notices/information were given by the club.
It's a great location - close distance to everything, and they are so refreshing - to have the greens and a pool - you'll almost believe it's not the UAE (some days).
At that time I think they were around 280K p/yr. But, again, I can't be sure.
Space wise it's good - you've got four good sized rooms, three with bathrooms, one a study with a balcony. And there's a maids room outside.
But, they weren't serviced for us. Maybe that's because the company had taken out a yearly contract - we also had to provide our own furniture.
But call the club and inquire about the apartments - it'll be worth it - they are a beautiful living.
