Lusk is a cheaper option to stay when you intend to visit Dublin. It is also close to beaches and good restaurants in Rush and Skerries.
Nicola's room was decent. There wasn't much space to move around in the room though. Also, the shower just gave out cold water for some reason. Sadly, I wasn't able to use the kitchen as it was messy but my bed was comfortable.
A decent stay for a night! :)
