My husband and I stayed for 6 nights at Paul's Place. It was just right for the two of us--had everything we needed to be comfortable. And Paul is easy to contact if you have a question. The weather was chilly when we arrived and he made sure we knew how to run the heaters so we could be warm.
When we travel, we prefer to make some meals "at home"--and the little kitchen in this apartment was convenient for doing so. There are shops in Glasthule and Dun Laoghaire where you can buy supplies, and the Sunday market just a few steps away in People's Park was a treasure trove of healthy and interesting things to eat and cook. That was a happy discovery. The apartment is very close to the DART station, so we were able to easily visit Dublin without staying in the busy city, but we also took the DART in other directions so we could expand our exploration. The medieval harbor in Dalkey was a pleasure to see.
Also, I've got to recommend the Wild Wicklow Tours as well--what a wonderful day that was! It was easy to meet the bus at its pick-up spot by the Dun Laoghaire ferry terminal. All we had to do was show up and away we went to see the beautiful Wicklow mountains and to learn about the ancient history there.
As an aside, if you are a James Joyce fan, the Martello tower where he stayed while writing Ulysses is just a short walk from Paul's apartment!
