An excellent experience, exactly as advertised. Very clean and modern, all amenities you could need are there (there's no dryer in the apartment, but the washing machine works like a charm) and you're located within a 20 minute walk of the downtown area and O'Connell Street. At $110CAD a night, you can't touch it for value in that location and you're getting a legitimately nice space to stay.
We used hop-on, hop-off, walking and taxis for our travels and never spent more than 10 Euros to get somewhere. Slice, across the street, is the only place we went on consecutive days over the course of a two-week vacation in multiple countries - it's that good. Maureen's is a small grocery across the street that has basic necessities as well. There are also many pubs, restaurants and bars within a five minute walk.
The only issue one might consider is having an understanding of how timers work for accessing hot water. We didn't, and as we didn't want to accidentally mess something up in the house we were reluctant to play around with the timer without contacting Ken first. We eventually figured it out, but Ken sent someone to check on us within an hour of my contacting him, which is remarkably quick in my experience on Airbnb. Again, this is in no way a reflection on Ken and Clare or the place itself, more for the traveler coming from a place where timers aren't often used (we came from Canada) and who wants to be comfortable.
Overall, a fantastic stay. One of the better Airbnb offerings I've stayed in and I would 100% recommend.
