Most of the appeal here is in the shared facilities. There is an infinity pool for adults and a separate kids' pool, so you are not trying to swim lengths around inflatables. For the end of a long day there is a jacuzzi, a steam room and a sauna, and there is a gym if you want to keep your routine going.
Children get their own space too. The building runs its own kids' club with a play area attached, which makes a real difference on a stay of a week or more, when the novelty of the apartment wears off. The building also has lounges for residents, useful when you want somewhere to sit that is not your own sofa.
Security runs around the clock, and allocated parking is included. That last point matters more than people expect in Downtown, if you are hiring a car or driving in from elsewhere in the UAE.
