I would recommend Susan’s place in Artane. It is located just outside the intercity area where you can book your tours. Bus stops to downtown are within a 3 minute walk. Grocery store, pharmacy and restaurants are located within a 5 minute walk.
Pub with great food 12 minute walk. Nice area.
Comfortable bed. Closet space.Nice shower. I was impressed. Susan is also a very nice lady and willing to help you if you have any questions.Breakfast in the morning
Is also a nice touch.
