I have explored it and returned back to it more than once, fabulous location and design and amazing views, the pool is extremely fun. This is far more like the idea I had that you could become successful and buy better apartments, cars clothes, weapons etc... it does have an elevator with a control panel you can turn on, but thereafter it does not work, if it's in the ending I presume the elevator might work but from what people say, you don't get to keep it. However if you can find a way to make it up there easier during gameplay, you can save game then log off there and will reappear there on logging in, and there is at least one mod in progress that will soon let you teleport to it. Will add some photos on another post soon. I've been careful not to take any of the objects or guns from the racks yet, but the most annoying thing (like everywhere else in the game) is you literally cannot sit down anywhere, no chairs, seats, bed, nothing is useable... no interaction at all - you can walk around and that's it, except for swimming in the pool. But watching the flying cars, taxis and aerial advert floaters crossing the sky from the balcony and seeing sunset/sunrise is a great visual immersive experience.
