We enjoyed our stay in Donegal. It is so close to so many dining/shopping options. We enjoyed The Quay on evening for dinner. We found if you go a little early (about 5), most places aren't too busy. Also, Donegal Castle is literally less than a block away.
It was wonderful to have both a washer and dryer as we stayed here in the middle of our 2 week trip.
In addition, the kitchen was well equipped and the living room was quite comfortable.
There were books and toys available for the grandkids as well.
