We really enjoyed our stay with Jamie. The apartment is beautifully situated - the location honestly couldn't be better and you have so much of Georgian Dublin on your doorstep as well as being in walking distance of the rest of the city. For a group of 4, we had enough space and were perfectly comfortable.
Others have mentioned the wifi / signal, which is to be expected for a lower ground apartment and as long as you're not working with numerous devices it shouldn't be an issue.
