James welcomed us with useful advice about restaurants and a play to see ("Once", which was great). The location could not possibly be more convenient -- it's a quick walk to just about every major site in Dublin and about 1000 restaurants and pubs within 1 km. The apartment is not glamorous (the photo is accurate) but reasonably sized and comfortable, with a full kitchen that James generously stocked with basic supplies, including a couple of cans of Guinness!
On the (slight) downside: the street outside is very busy, quite noisy and brightly lit all night; the view out of the window is of a vacant lot being used as a car park (but with the Castle just beyond). If you want to open a window -- necessary in the summer -- then you will want earplugs and eyeshades.
