My family and I enjoyed our time in Connor's home. It was pretty much as advertised. We only spent a night, so didn't we didn't really use any of the appliances and can't speak to them, but everything we did require was in good working order.
One note - if you're traveling with heavy luggage or anyone with mobility issues, this would be a difficult space because there are stairs to each of the bedrooms.
This is also in Ballsbridge, which was great for what we wanted to do during our time in Dublin, but it is further away from city center.
