I just recently moved to Arizona from Irvine, California; my Apartment at Liv easily rivals my $1,800 1 bedroom apartment in Irvine and in fact my Liv Apartment is much nicer.
In terms of the staff, THEY ARE AWESOME! All of the staff are very helpful and responsive to any request. The staff here is friendly and treats you like you are another person and not a number.
I can't recommend Liv enough, if you are looking for a excellent luxury apartment then look no further!
