Regarding the shower rental service - its convenient to freshen up between long flights or layovers. After getting off the plane, the shower is located airside, so carry-on your change of clothes/toiletries. Its pricey and small but modern and clean, basically its renting a efficient private full bathroom to have all to yourself for 45 mins. All the basics are provided - towel, shampoo/conditioner, body soap and hair dryer. There is unlimited hot water but its on a timer so just have to press a button every few minutes to keep water flowing.
Took one star off because there is no advance reservations, first come first serve so I had to wait 45 mins for one to open up (mid-week at ~7am). I overheard folks behind me in the line got a 1.5+ hr wait time. So show up at this counter asap, then go grab a quick breakfast/coffee while you wait if needed.
While not related to this hotel, there is also locker service at another part of the airport (near ground transportation). So after my refreshing shower, I was also able to store my carry-on at the airport (with my dirty clothes/toiletries) at a very reasonable price and explore the city without all the bulk...win win! read more
