Rayz hotel was fantastic; the staff were friendly and helpful; they even got us in a little early. The inside looked beautiful! We booked this hotel to have the view of the Eiffel tower, and wouldn't you know it, we could ACTUALLY see the Eiffel tower. The view from the top was spectacular!
There were just a couple things I personally didn't like: the elevator was small, myself being claustrophobic it was kinda hard to be in it. Also, we booked a "joining room" so the adults could sleep in one room and kids in the other. The only thing was, the doors weren't able to lock open so we kept having to use our key cards to get from one room to another. And there was a third door that blocked both the doors before getting to our door (I'm guessing in case we got too loud going in and out), but it made a tight triangle shape when inside all of them and again, claustrophobic.....Other than those personal feelings....
Would definitely recommend Rayz!
