I'm writing this review from the perspective of a parent with young children.
The place is in a great location for access to food and shopping (it's very close to Toys R Us and the bus stops), but be aware the unit itself is on the 4th floor (if you start street level as 1) -- strollers might not be so convenient. It does fit 3 adults + 2 kids comfortably. The AC works well with the main split system able to cool the entire unit.
Wifi did not work for us while we were there, so I can't comment on that.
In regards to the safety issues:
The stairwell leading up to the unit is dimly lit and has no security gate. Also, although the stairwell itself is wide, the stairs are thin/narrow so tread carefully.
There is no deadbolt, so security is very minimal with just a basic door lock. We used the sofa bed in the living room to block the door each night.
The beds are located directly next to windows that open (for fresh air and to allow you to hang clothes). This is very dangerous, and I recommend any parents with curious children to watch them very carefully while on the bed/near these windows.
All in all, the place is a good value but be wary of the safety issues for the little ones.
