This is a sweet place with lots of character. The hosts left a basket of food and stuff in the fridge if needed. They were very thoughtful. The home was neat and cozy and very homey.
Things to note: There is one bathroom that is on the first floor. The bedrooms are up a metal spiral staircase. If you have mobility issues, this might not be the place for you. Also, the area with the restaurants near the water is really nice both for eating and for strolling. It is behind the buildings across the street.
In order to communicate with international hosts it is easier if you have an international enabled phone.
Have fun. Dublin is an extraordinary international city with a variety of neighborhoods and areas to explore.
