So, I've now stayed at this and the Avagard capsules hotel that are also in the airport at BKK. And I have to say Boxtel is by far the better option. So, if you're looking at both, definitely go with Boxtel. The main problem I had with the capsule hotel was that it got extremely hot. The tiny fan couldn't keep up with the radiant heat from my body and it got so hot overnight that I couldn't sleep. The Boxtel room's fan was much more powerful and the larger space meant I had no issues with heat. I will say, that I don't think either option has true "AC" even though they list it. In reality I think they both just have fans that blow air from the terminal into the space. Again though, the capsule hotels fan was tiny and did almost nothing. Of course, not having a bathroom/shower as part of the setup is a downside, but there are restrooms nearby in the terminal. If you're just needing a place to crash between flights, these Boxtel rooms are a great option. Don't choose the Avagard capsules over this if Boxtel is available. Also, just in case anyone is looking for this info, this is located outside of the airport's secure area, so you do have to clear customs and immigration to use them.
