All previous reviews are completely true. Great place to stay, excellent breakfasts, perfect communication about check-in and tips for what to do, close to everything you want to see and not to forget a very comfy bed.
A few tips: take the train (30 minutes) to Howth, a charming fishing vilage with nice cliffs to walk on. Great food and nice wines in a modern restaurant (Beshoffs) next to the harbour (100 metres from the train station).
If you like Italian food try Di Luca which is just a few minutes walk from Susan place. Walk towards Ryan's, cross the road and turn left at the end. Great wines and delicious food.
Enjoy your time in Dublin!
