Just returned from a week in London, then a week in Dublin. I had a horrible experience with The Henley House hotel in London. DO NOT STAY THERE! I've done a fair amount of traveling, so I know some considerations have to be made, but the employees were the rudest people I've ever had the misfortunes\ of dealing with, the room looked nothing like what they promised I would be getting (and they refused to move me to another room.) I regret staying there, and giving them my money.
On a positive note, found a GREAT hotel in Dublin: The Cassidys Hotel. Great location,fair price, and very helpful friendly staff. That will be the only place I stay whenever I'm in Dublin.
Slainte!
