John's apartment was just ideal for three of us visiting Dublin for the first time. It was easy to find and the arrangements for picking up the keys worked well. As others have noted, John had helpfully laid in some basic supplies and there was useful local information as well as access to TV channels and films for the times you are not out exploring.
Although the apartment is opposite the Irish Times (good fun watching the journalists work) and next to a pub it is not noisy and we all slept well in the comfortable beds.
The bustling shopping and entertainment areas are only about 5 minutes walk away, as is Tara Street Station where the local trains will allow you to explore north and south along the coastline.
This is a very good property with a very thoughtful host, and we certainly hope to stay here again one day.
