For our early international check-in, we wanted a place close to the airport that wasn't the usual, generic, airport hotel. The Grand fit the bill. It is an old hotel on the Irish Sea and looks like it was last refurbished in the 1960s. (The lobby and restaurant, where we had an afternoon snack, looked like it was designed for the "Mad Men" TV series). Yes, our room was small. Yes, the window looked into an air shaft. But heck, we didn't pay for an upgraded room. The view from an airport hotel wouldn't have been any better!
The reception clerks were very nice and helpful. The hotel was only two blocks from "downtown" Malahide (where there are lots of dining choices). A veranda overlooks the marina. Our room was fine, albeit small as other have said. The hotel was just what we wanted for our last night in Ireland. The airport was 15-20 minutes away, and on the route there were several gas stations to fill up the rental car.
