seeking cheap hotel near piraeus-athens airport metro line

hi - simple query :-)

family of five, that due to irreconcilable differences between airline
and ferry timetables (:-) will need to spenfd a night in athens prior
to flying home, in summer of 2005.

Seeking a cheap, quiet, clean hotel (3 children under 10 years) close
to the piraeus-airport metro line.

any recommendations?

cheap is a relative term I appreciate ... so just tell me what _you_
know and I can decide if that is cheap:-)
many many thanks in advance
