We stayed in the apartment of Marie for three nights. The accommodation was very nice and the hand-over of the keys worked flawlessly (most certainly due to Marie's excellent descriptions). Also we never met Marie in person, she was a very nice host, asked if everything was alright and even left some drinks, chips etc for the guests.
The location of the flat is very good. You have a supermarket right around the corner and the Jameson distillery is 2 minutes away. The ride to the Airport took around 30 minutes.
It was our first stay in Dublin and I would without hesitation recommend Marie's apartment.
