We stayed 4 days and it was an amazing experience! The location is great, the staff is very friendly and helpful and it's only about a 15-minute-walk to the city centre. The hotel is right beside the canal in Ballsbridge and it's peaceful.
There is free wifi and even free movies. You definitely won't get bored.
It's also very easy to get there as there's an aircoach-stop right outside the hotel.
