Stayed with Claudia and her family for more than month and it was great experience. There is a private bathroom a room itself is cozy with solid desk and comfy chair so I had no issues to work from home.
Room has also pretty nice view on the sea. The location itself is perfect - 15-20 mins to Tesco/Aldi. Walking distance to buses and dart station plus Blackrock park and Sandymount Strand.
