Very clean and quiet hostel that is a cheap cab ride from the airport. Rooms were simple, spacious, and cool. The front desk staff was extremely helpful and spoke very good English. The surrounding neighborhood is mostly residential though, so it is best to eat before you arrive (a nice simple breakfast is provided).
If you are taking a cab from the airport, point out the directions to the translators. My cab driver was confused about which KingKaew road to take (don't take 58/1 or 58n), and he only reluctantly continued on when I was persistent.
