Stayed there couple years ago for a week with friends. Our flight was delayed in Dublin so we arrived at around 11pm, but the owner was kind enough to collect us from the airport (for a fee of course which seemed a bit steep but still it was a nice touch).
Very nice place about 20 minutes walk from Old Town away from the tourist masses. We booked the room for 3 people, but we got room with two single beds and a fold-out bed which wasn’t very comfortable. We did have a private shower. Very simple – room only, no frills, cheap accommodation, lovely patio outside overlooking the see for few evening drinks bought in the nearby shop, lovely pastry shop just down the hill. Room was clean when we checked in and cleaned several time during the week. We never saw any of the family or hear any other guests during the night.
Judging by the previous reviews we got very lucky as we had no problems with this accommodation. I would definitely recommend it!
