While I really enjoyed my stay at The Marlin, it needs to be clear that they DO NOT OFFER FREE CANCELATION! I contacted Expedia to simply change the dates of my trip, as my dayghter was able to meet me in Dublin but it would require a change of dates by a couple of days. I was told the hotel would charge me $199 to cancel my reservation or $359 to move my dates and add a day. This is not acceptable for a hotel to basically hold your hand to the fire and falsely advertise free cancelation and not honor this. Again, I was not trying to CANCEL, just simply change the dates well in advance of the "free cancelation" window.
The hotel itself was clean, modern and in a very walkable distance to Trinity College and central Dublin. Staff were nice and attentive. Even my small Cozy King room was more spacious than expected, having stayed in NYC previously. It was more than ample for two people with luggage.
The hotel either needs to honor the free cancelation or be honest and upfront with their $199 charges.
