When you first pull up to Sakaeya, it doesn't look that impressive - and the lobby looks alright, but nothing amazing.
Then you go upstairs. Wow! The hallways are beautiful, and the porter leads you down to your room (to which they've already taken your luggage for you while you were checking in). Our room was absolutely beautiful - the A/C was already on, background music was playing inside the room, and it was the nicest room of our entire trip for sure (and definitely the fanciest Washlet of all...it even opened its own lid automatically when you opened the bathroom door!) The on-site onsen was also lovely - we made sure to use the outdoor one - and the walking route to the 9 public ones was nice and close too.
