Looking for accommodation in Dublin; September - December 2008

I’ll be coming to Dublin in September ‘08 to attend a 3 months fellowship in musculoskeletal radiology at the Mater Misericordiae Hospital, Eccles St, Dublin 7. I am looking for affordable housing preferably close to the hospital. All I really need is a quiet, non-smoking room (preferably with internet access and a place/desk to study) in a safe environment. I’d be very grateful for your help and good advice. Thanks for reading this message.
