OK, so you’re not flying in to Cork, then? We did in the springtime two years ago, and the bus ride into town was easy and close. How are you getting from Shannon to Cork? After we had several nights in Cork, we took the bus back to the Cork airport to rent our car for visiting more of Ireland. We flew out of Ireland from Shannon, BTW.
We had an Airbnb up the Summerhill N road, northeast of downtown, on the north side of the River Lee. It felt a bit suburban, where the local residents lived, with plenty of restaurants, although we also went into downtown some nights for dinner, including at the outstanding Goldie restaurant (make reservations). It was a bit of a walk to downtown, the English Market, the Crawford Art Gallery, the Butter Museum, and many music pubs, and we took a taxi a couple times, but walked the rest of the days and evenings, and the price for our small studio place was certainly right. We were also a few short blocks from a nice local’s pub, the Belle View Bar, on Old Youghal Road, where the talented owner and his band played one night a week.
I don’t know what lodging options are there, but if you really wanted to be “in the mix” of things, I’d look at the pedestrian, somewhat gentrified area around the Goldie restaurant. Otherwise, our Airbnb area in Summerhill was very good.
