Very close to the Dong Muang Airport, less than 10 min by walk. Very nice owner, who welcomes you with smile and warm hospitality. Very clean facilities. Very nicely designed, stylish compounds. Probably, the very best hostel around the airport for a nap after a late flight or before an early flight. Highly recommended.
(NOTE for booking issue: I booked a capsule in a mixed dorm on Japanese Hotels.com. There was a system error on the site, and my booking request went to the hostel as I will stay in a female dorm. This seems to have happened several times for Japanese guests, yet Hotels.com had not fixed the system error. Thank God, I noticed the system error by myself as I double checked the email notification of my booking status which says my capsule is in female dorm, although I booked one in mixed dorm and it was shown on the booking record of my account of Japanese Hotels.com. I contacted the customer relations section, but their response was very very poor. I had to call them three times until they called the hostel for confirmation next morning, just few hours before my flight schedule. You can imagine how much it was frustrating for me.)
