The cottage is a row home, connected on just one side to the next cottage. The community it is in is surrounded on all sides by the St. James hospital, where they are doing a massive amount of construction.
There is a bus line not too far away, just outside the community, but if you want to get one of the hop-on/hop-off buses you'll need to walk over to the Hilton (12ish minutes) or over to the Guinness storehouse (10ish minutes). The tram has a stop at St. James Hospital which is only about 4 minutes away. Walking to the downtown area (Trinity College being at the heart of the downtown as the shopping areas and Temple Bar are immediately adjacent to it) takes roughly 35 minutes.
The cottage itself is nice though has a lack of airflow which was my primary complaint during the heat wave. The bathroom door refused to latch but is well balanced enough that it would stay closed. The flooring in most upstairs rooms is wood plank, not traditional hardwood flooring as there are gaps between planks, except in the bathroom where linoleum was put down on top of the planks; this causes the flooring to be a bit wavy/uneven.
Overall this was a nice place to stay and if there was something to keep the air moving I wouldn't hesitate to go back.
