It's an OK hotel
It's an OK hotel, but there are a few very annoying issues.
1) I assumed the hotel was inside the airport. I was looking all over, but even when an airport info center employee explained to me how to find it, it took me a while to realize that I need to leave the terminal and cross the street to enter the hotel.
2) They are all electronic. This would be OK, except that when you travel internationally you might not want to switch your phone on to avoid expensive roaming costs. This happened to me. When I checked in they sent me the codes over email and on my phone, which was off for the said reason. The airport has free WiFi, but it's another quest to connect to it. Basically you need to find a terminal that would print a ticket with access code when you present valid boarding pass.
3) After all this more troubles followed. I was entering the code countless number of times, but it did not open the door. Little did I know that after entering the code, I needed to press another button on the electronic lock. There was no instructions about how to use the code. With the help of an employee, I was able to get into my capsule.
4) The ladder to the second level capsule is very inconvenient. It's hard to explain, but trust me - you can easily fall from it when getting in and out.
Other than that, the hotel is not bad. Given that the price is close to a room price in some airport hotels, they could do better.
