Had a great experience here. Yes, the bar is dimly lit, yes the corridors are also dimly lit, but it's not that there is something to hide. It's purely to create ambiance. In the evening little tealight candles are scattered throughout and along the steps on stairs which adds to the feeling. The main entrance on the quayside does bring you straight into the bar which, in order to get to reception, you have to walk through. But there is a clear designated walkway to follow that is set apart and runs parallel to the bar seating area - so you are not actually walking THROUGH the bar as some reviews might have you believe. Alternatively, there is a side entrance (Jervis St side) that brings you straight into reception.
Check in was a breeze - very efficient and polite staff. We were asked if there were any special requirements and we said all we needed was a taxi for 8.45pm to bring us to the restaurant we were visiting. Reception said no problem - they would book one for us.
The room was perfectly fine. Ok, wasn't a room with a view (back of hotel) but that wasn't important to us as we had plans for the evening.
Loved the fluffy robes, slippers, bathroom smellies etc. Comfy bed, great big pillows, sound system, flatscreen interactive TV, etc. Really, nothing to fault at all.
We took our aperatif before dinner in the bar. Again, faultless. Background music was of the chilled variety.
And as promised by reception, our 8.45pm taxi arrived.
Upon return from dinner, we went back to the bar for a nightcap and then went to bed - before which we decided to have breakfast in bed the next morning. So we filled out the menu card and slipped it on the door. (This was well after 1.30am).
Breakfast was served promptly at 9am (after a brief phone call to warn us it was on its way). Full Irish which was not greasy at all. Excellent I would say (and I'm Irish so I know what a fry is all about). We also had cereal, toast, croissants, juice. Really was fresh.
Check out was also no problem. Very gracious front desk staff.
All in all, a great experience. Not cheap, but then again Dublin these days is not cheap. I found it worth the added few Euros as it left us with a good impression and no hesitation in returning. If Laura Ashley is your cup of tea and middle England, then the decor/style may not be for you. But we found it bordering more on the hip/contemporary without being too much either and in keeping with Dublin's young modern vibe.
We didn't eat at the restaurant itself so we cannot comment.

Stayed here for 2 nights on business following recommendation from a colleague - loved it ! Very chic hotel - design by John Rocha. Very friendly and efficient (Irish) staff were most helpful. Rooms are well equipped and very modern, with lovely toiletries provided ( Irish again ) and a well equipped bar and tea/coffee selection.
Restaurant again very chic ( dramatic actually ) and breakfast buffet spread was fab. Everything from full Irish cooked breakfast to good selection of fresh fruit and pastries - definately something for everyone. Business or pleasure, the Morrison has a very central location, right on the banks of the Liffey and less than 5 mins walk to the Temple Bar area. Highly recommended.

Contemporary hotel right by the river, walking distance from everything, close to the popular Temple Bar area. Everything you need, free wifi at time of our visit, comfortable leather sofas in lounge overlooking street/water to read paper and have coffee and cake. Clean, pleasant, friendly, helpful, priced right for Dublin, well located, and most of all unintrusive. 3 blocks from airport shuttle drop-off (12euros). 5 min walk to St-Steven's Green (park with lake, ducks, etc.)

The Morrison may appeal to travelers looking for a great location with easy access to the strolling the bar area as it is just across from the Temple Bar area and easy to get to other city attractions. But it is not recommended for the business traveller because its all style and no function. Arriving at the front door which is a sparsely and darkly decorated bar, we were all a bit confused as to where to find the check-in which down a dark hall. Once arriving there, the check-in was quick and the staff exceeding friendly and eager to please. The elevator was small and so dark and stepping out of it was even darker - why does the hotel think dark is style? Is the hotel actually so dank and dreary they don't want to turn the lights on? Do they think the over-sized mirrors in the lobby compensate ? I literally walked into a an open service cupboard door in the dark area leading to the corridor to the rooms. The room is also dark with ineffective - but stylish - lighting. It was impossible to put on make-up! Fortunately there were good reading lamps by the bed. The room has a modern, dark, sparse style but lacks function. The narrow long table is ineffective as a desk (lacking working light) - and there is only a little stool making it almost impossible to sit and work. But there is a lounge chair for relaxing. There are NO drawers or shelves for stowing clothes - only a hanging closet without shelves. There were two very shallow, narrow drawers under the narrow table but even the staff couldn't unlock them and they certainly wouldn't accomodate more than a thin pad of paper. There was no stand for a suitcase which had to lie on the floor in the rather small room. There were no towel hooks or hangers in the bathroom - just a hook for the bathrobe so the handtowels just lay on the little stool. The above the counter basin sprayed water everywhere when washing hands. The toilet paper holder didn't hold the toilet paper which was always on the wet floor. The little holder for soap in the shower was made of wire too wide for the small bottles of shampoo so they only fell over. The breakfast was pretty mediocre by European standards. Two of the three mornings I came down, they had not set it up by 7:20 (although it was supposedly open at 7) and when I came at 8:30 they asked me to come back in 20 minutes because they had no places. But the staff was very friendly and the location great so stay here to party if you don't mind the dark and don't have much clothes. And the bed was big and comfy!
