This secure and secluded gem in historic Kilmainham is a perfect base for a single person looking to enjoy Dublin city, but who also wants perfect peace after dealing with the stresses of the day. It's not large, but it has everything you want, including a outdoor seat to have the first cup of coffee of the morning.
I was allowed check-in an hour early, as I needed to drop my backpack before the rest of the day. That was a great help. Public transport (and a bike share stand) as literally around the corner.
Make sure to use the water from the outside tap for drinking! And enjoy!
