About a 40 minute walk from Temple Bar and central Dublin, and a 10-15 minute walk to buses and a bikeshare station (you can pay 5 Euro for a three-day pass). It's also a 30 minute taxi ride from Dublin Airport.
The room itself is cozy with a stove, microwave, and fridge. It was a little cramped with our party of three and the pull-out futon in the lower level was a bit short for our tall party member that slept there. The upper level has a comfortable mattress and good space. The access point is a ladder so definitely only recommend for those comfortable climbing up and down.
Eddie was a great host with lots of helpful information. The room is next to Phoenix Park, which has a zoo, we heard the lions at night!
