I'm a 66 year old retired school teacher from Canada. My wife and i are going to spend a week travelling in Ireland but she wants to visit with our latest grandchild in England. i want to continue in Ireland for a few extra days. I'm going to try hostels as a way of keeping my costs down. I've never done this before. My concern is how can i find a quiet hostel in Dublin that is not too expensive and where i won't be the only senior citizen.
