Unless you have to be in central Dublin i would avoid and come out a bit far more value around .

I stayed at Premier Suites Dublin (Leeson Street). Got a really good last-minute deal. Great location by St Stephen's Green - and the airport bus stops right outside.

Harcourt hotel was cheap and central.

Camden Court Hotel is quite pleasant, just south of the river. Bleeding Horse pub next door is nice too

Those premier suites are nice, Stauntons on the green have deals sometimes. Need to be central?

cheers all

Clayton Cardiff Lane was good, i personally found the Harcourt grim. Was cheap though. There are 2 buildings, from their photos one is nicer than the one I stayed in!
