Agreed Tel, if you weigh up things overall, and I've stayed at dozens of places in Bangkok around the 1000-1500 price range. Nasa Vegas is a bargain. It's not dirty, it's secure, the security in the lobby do keep their eyes open, there's always a taxi outside (not rip-off) and it's an ok location. Most taxi drivers know it.
I ended up here last year because I'd landed at the airport still pissed from the flight and wanted to get somewhere fast and nearby.
