The location is very good in terms of access to local points of interest, to Dublin, and to Wicklow - our focus was on visiting as many Wicklow gardens as possible in 4 days. We succeeded (we would recommend Mount Usher, the Blakes' gardens and the National Botanic Garden at Killmacurragh).
The bedroom and living room are spacious, the chairs and bed are comfortable. The kitchen has enough for light meals, and Dalkey has some great places to eat - eg the Jaipur.
The tv gives access to a wide range of programmes, films, etc. Good after a hard day's tourism.
The hosts are friendly, helpful and flexible.
