Great value for a group! There are 2 bedrooms, the back one has one double/queen bed and one single bed. Then the other room has a king size bed and 2 chairs that unfold to beds. In the hallway there is another unfolding bed. The regular beds are comfortable and clean. The unfolding chairs are less comfortable but okay for kids.
Location was amazing on Fitzwilliam Square! We walked to everything! Grafton street, tours, etc. We stayed for 10 days and were pleased that they came and changed the sheets/towels mid stay. They offered airport pick up service as well, which was easy and reasonable. The place is owned by a company not an individual so check in was at an office but quick and easy. There is visible mold on the bathroom ceiling so I would not recommend for anyone with breathing issues.
The showers have electric heaters, works great, but get directions on how they work. There is a washer/dryer combo in the kitchen which once we understand it works great! Overall this was a great location and value for a large group and provided 2 bathrooms which was great! The stairs down are steep, so be aware of that.
