If you are forced to spend the night near Suvarnabhumi airport, this isn't bad. Free pick up at the airport, and they drop you off there for your flight- it is about 10 minutes away by car. Nothing fancy or special.
Breakfast extremely basic, but satisfactory.
If you want to sleep in I don't recommend this place, as there are very loud chickens which begin crowing at dawn (aka 5 am), and it would be impossible to sleep through that.
The location in downtown Lat Krabang is nice though because there are lots of really cheap Thai restuarants and outdoor bars very close by, and a Thai temple across the canal a little bit to the northwest of the hotel.
I don't think there's a better option, for such a cheap price anyway, near the airport
