Someone asked me about this picture from my blog header.
So to answer the easiest thing would be to refer them to this post from last summer. The picture is of Isaacs Hostel in Dublin. We stayed there during our trip to Ireland. You can read about it here: Ireland and More Ireland
Never say you are too old to stay in a hostel! Do your research, read reviews, search Google for blogs that talk about where you want to stay, and then contact them directly with any questions you have!
