Sean is great and the flat is as clean, comfortable and well furnished as the other reviews say.
A couple of details:
Dryer not currently working (washer is fine)
Hall shower has red switch outside door to start hot water
Master shower water control is counter intuitive (to me). Turn the lower knob handle toward the red on the left for cool water and to the blue on the right for hot! Go figure.
The window curtains in the bedrooms are pretty but unlined and at this time of year with dusk around 10pm and dawn around 4am, that can be disruptive when trying to deal with jet lag.
We loved our stay here and would definitely recommend to others and return if we found ourselves in Dublin.
Note: Trinity College, Dublin Castle, Grafton St pedestrian district etc. are 15-20 mins away on foot. Taxis are plentiful but traffic can be very heavy and can take longer than the walk.
Nice Fresh grocery store and cute bakery very close.
