Daragh met us at the apartment and provided parking vouchers for our rental car so we could settle in quickly.
He was very friendly and suggested several sights we could visit as well as a pile of maps and brochures.
The apartment is in a fantastic location that is close to the centre of Dublin and perfect for exploring on foot (we did not need to use our car at all).
Plenty of room in the apartment for the two of us and great cooking facilities. No lift in the building but only a couple of flights of stairs.

Only downsides were a smell in the apartment (probably from the previous guests cooking) that took a day or so to dissipate despite having the windows open. Also the noise from the main road below was very noticeable especially at night (even with the double glazed windows) - we had to resort to earplugs to cope. Be aware though that most accommodation this close to Dublin centre is going to have a similar problem.

Overall we were VERY happy with the apartment and fell in love with the city. Dublin is a fantastic place to holiday and Daragh's apartment would be our choice if/when we return.
