I actually found the Marine by accident. I'm glad I did because the whole experience was awesome. The hotel was built in 1897 and has the classic lines and architecture of the time. The views from the rear of the hotel were amazing Irish sea views that are available in the lobby and dining room. We didn't get a sea view room because they were all booked.
Even though our room was on the front of the hotel closest to the street, our room was super quiet. Since there is no air conditioning in the rooms, we opened the windows and still wasn't bothered by noise. We were there in early May, so the weather was perfect for sleeping with the windows open.
We ate the breakfast buffet every morning. It's simple fair of egg, sausage, bacon, hashbrowns and a bread selection with local jams and butter. Of course, hot tea, coffee and multiple juices. Everything was fresh and always full. We also ate supper two nights and the food was excellent. Theres not a huge menu selection but it was more than adequate.
The bar was as cool as the rest of the hotel with a decent liquor, wine and beer selection. The bartender is a real worker who buzzed from one end of the bar to the other, always attentive and knowledgeable.
Our room was clean, large and comfortable. One small complaint was the bed. It was a little on the hard side.
When we make it back to Ireland, I would not hesitate to stay at the Marine or recommend it to friends or family.
