You need to book Marie's place if you really want the true taste of Dublin. It's right in the middle of everything, so easy access to all the top bars and restaurants, as well as mass transit such as bus stops and even the Connolly train station (12 minute walk). The Guinness Store House as well as Teeling Whiskey Distillery are both within walking distance as well.
As far as the place itself, it literally sits atop The Temple Bar so it's great people watching the most visited bar in Dublin. It never really got that raucous when we were there - but even if it did, closing the balcony door provides instant sound relief. Even better, the bedroom is on the interior of the building, so we didn't hear a thing come bedtime. All the amenities are present that you would expect in a 5-star rated place. Huge couch to spread out on. Nice big bathroom and shower. The nicest extras were the numerous fans Marie had all over the apartment. I think 3 in the living room and 1 super strong fan in the bedroom. It certainly helped keep the apartment cool during the middle of the day (we're from Minnesota so we like it cold).
Just be forewarned, it's 4-5 flights of stairs up (no lift).
Check in and out were a breeze. Marie responded very quickly to any questions. Overall a very pleasant Airbnb experience. We highly recommend!!!
