What a cool spot right along the harbor in Howth! We stayed here to be close enough to Dublin to get there with ease (thanks to the DART station < 10 minutes walk away) but to be a little quieter and easier to park our rental car. Howth itself has lots of cute seafood restaurants and cliff walks nearby that are worth a visit in their own right.
Brian was a fantastic host - supplied us with extra essentials for our baby, had fresh juice and milk/yogurt and coffee pods ready to go for us. He is fast at communicating and accessible, yet you have your privacy with a separate entrance to the unit.
You do pay a little bit for the great location to getting some road noise from the main street below, if you are a light sleeper. But that proximity is really awesome otherwise!
