Thanks for your input, quillber.
You're right. Originally I was set on the Ballsbridge area but I think I'm finding myself a little more flexible at this point. I still lean to the South side based only on what I've read on this and similar travel forums. Clearly I won't make a final decision until after I arrive.
I have been looking at the daft site and there are some choices in the short term section. Should I contact agents in the "long term" section as well to see if they might be interested in letting one of their long term properties for a shorter term if I paid upfront for the entire 4 or 5 months? What do you think of this alternative tactic? Worth my time or waste of time? There are obviously a lot more choices in the long term section of daft.
