Lobby and rest of the hotel is really good. We checked in really late and the area around the hotel was not all that great for a late night. Parking was pretty painful

The reason I give this property 5 stars is because if the staff…Keva (sp) was amazing, we were 2 senior ladies and she could not have taken better care of us. She is helpful, kind, patient, funny and just the sweetest young lady. The rest of the staff, unfortunately I don’t have names we’re all very nice. The low rating in communication was more with Expedia.com I believe, not communicating our requests to the Hub. We tried for 2 weeks to add a day at the beginning and end of our booking and it was never addressed as far as we were told . The location of Binary Hub is good for walking to anywhere downtown, its student dorms so the rooms were small but clean and adequate for what we needed. Large kitchen area and large comfortable common room.

The hotel was great for transport links. Bus stop very close by. Was disappointed that the shower was over the bath. Would of expected a stand alone shower. Breakfast was fine but we didn't see the menu options to order eggs or waffles until the last day as nobody had told us. Only one working lift which means long waiting times at busy times.

"I had a great stay at the Marlin Hotel in Dublin and would happily recommend it.

It was the perfect balance: peaceful, yet within easy walking distance ..."

4.5/5(56 reviews)

Croke Park in Dublin is so much more than an impressive sports stadium. “Croker”, as it is locally known, is in many ways is a bastion of Irish identity that protects the spirit of Gaelic games from forces seeking to dislodge it. If this all sounds a bit dramatic you should take the fantastic Croke Park Experience tour to get a very real sense of just how important and deeply ingrained the GAA and Gaelic games are to Ireland’s sense of itself.
