We stayed 3 nights and had a blast in Dublin. The flat was located just about 1/2 a mile from oconnel street (one of the main drags). From there we walked everywhere; Christchurch cathedral, st Patrick's, Guinness tour and temple bar. It was a bit of a hike, but the flat is in a great location to explore the city. There are several bus stops along the way if you didn't feel like walking.
The flat itself was clean and had everything we needed. The building itself was very quaint and was next to a great park. Dorothy was also very attentive and responds within the hour. All and all this was a terrific value for this flat!!
P.S. if staying in Dublin eat at PHX. About a mile from Dorothy's flat and well worth it. The gnocchi might be the best thing I've ever eaten. Cheers!
