My girlfriend and I turned up in Enniskerry in December of 2009 after a whistlestop tour of the top half of Ireland (inc Northern Ireland). Perhaps my ratings seem a bit over the top but I honestly couldn't fault this place. Sure it was the most expensive night of our trip but I just can't fault any of it. The inn is located right in the centre of Enniskerry, a small but gorgeous little village south of Dublin. We just could not believe that we were so close to the capital but in a place that seemed so secluded. We visited in December so the streets had very tasteful Christmas decorations all around. This place is also a stones throw from the Wicklow mountains - an absolutely stunning part of Ireland's scenery.
We turned up at the Powerscourt Arms having decided to pay the 70 EUR for two people Bed and Breakfast. This was hardly a bargain basement price but we got what we paid for. The only thing warmer than the inn (this was in sub-zero temperatures so warmth was a major plus point!) was the welcome we received. Standard lovely Irish welcome that extended into our departure the next day. The place is so cosy and everything just seems clean and functional. The bed was a king size I think, very soft with soft carpets. The bar was very nice with a good selection of Irish drinks and the restaurant also sold some nice food.
Overall I was very pleased with this place hence the gleaming review (my first 5 rating on this site). I have stayed in four star hotels a lot worse than this. If you're going to Dublin, Wicklow or Enniskerry then a night here is a must.
