Mary is a wonderful host, with many recommendations that she's happy to share! The studio is warm, charming and well appointed. We had a great time and wanted for nothing.
The studio is a roughly 10 minute walk to the lovely village of Dalkey - with it's excellent restaurants/pubs & some nice local attractions - and about an 8 minute walk to the DART station to get you in to central Dublin (about a 35 minute train ride). If you're looking for a break from being in the heart of a city, yet close enough to spend the day there, this is it!
One minor note of caution - We found out the hard way that the DART service to the area ends around 11:30PM (depending on the station you're coming from), so do plan accordingly if you're planning on soaking in some of Dublin's nightlife.
