Had an overnight connection on the way out of Vietnam and this beat a 15-25 minute cab ride to a hotel. I was a bit skeptical given that it was in an airport terminal but everything worked out fine.
The Sleep Pod is near the exit on the right side of the terminal, across from the public restroom area. Assuming that you are getting there late/leaving early it is highly likely there will be no foot traffic where you are, meaning it is quiet and relatively private (again, given that it *is* in an airline terminal).
The pod was quiet, bed comfortable enough, and just enough room to get ready. Some basic toiletries, snacks, and drinks were provided so you weren't forced to open your suitcase if you didn't want.
While I didn't know what to suspect, I got a good night's rest and didn't have to fight with morning traffic to catch an early AM flight.
