Pretty straightforward experience, especially after reading all the comments here.
So, be aware that the key pick up bar is at the beginning on the corner of the street, before the garage entry. Important cuz if you pass it, you end up in a jammed up street and it takes you forever to get back to the starting point.
Bigger cars indeed need to manoeuvre a bit in the garage.
... and the elevators don't work, so to get back into the garage you'll have to take the car entry.
That's also my only minor negative comment, since it would be nice to be notified about this in advance. Not a big deal (again, it was already stated here in comments), but it would just make the experience even more pleasant.
Close to a subway, so all in all, definitely recommended!
