Ian's place is in a nice quiet area in Dublin. It's a short walk to the Jameson distillery and a 20-25 minute walk to O'Connell Street (the main street). When we arrived Ian was there to greet us and was friendly and offered some good suggestions for food and attractions.
The flat itself has two levels and it's own entrance. On the first level is a bathroom, kitchen, living room, and a small outer space (kind of like a conservatory). Upstairs are two bedrooms with one of them having a bathroom.
The bathroom upstairs doesn't have very good water pressure and the tub is very slippery. If it's just a couple staying there, I would recommend using the shower downstairs as the pressure is a lot better and it's a standup style shower.
Note that the steps going up to the bedrooms are steep, so be careful when going up/down them.
