That isn't true.  5 star hotels are roughly the same all around the world.  If it is rated 5 stars it will have at least the same list of amenities that all 5 stars have.  Some 5 star hotels can still be nicer than others or offer more stuff than others.  Some can be in new buildings and some in old buildings but they all offer the same minimum standards of service to be 5 star.  I have stayed in hotels in Toronto that are nicer than their equivalent in Europe and vice versa.  There is all sorts of apartment rentals of every kind in Toronto.
