Stayed here recently for a night with a friend who was in town on business. The hotel positions itself as a boutique offering, and generally lives up to the tag. Friendly staff on arrival, and an efficient check in service. The room was good - twin beds, with enough space, although rather small bathroom.
Downstairs bar was great if somewhat pricey - good ambience, which is often lacking in hotel bars. The bar turns into the breakfast area in the morning, which was a good all round buffet offering.
Location is really good IF you want to explore the Temple Bar area...if you want pubs and restaurants and entertainment at your doorstep, then this is the place for you. If you are looking for peace and quiet, then this is definitely not the place for you - lots of noise in the street and hotel itself. Personally, being there for only one night (and arriving back at 2:30am), the noise wasn't an issue for me. Another good point was the price - Euro 117 (prepaid internet rate) was pretty decent I thought.
So, I would recommend The Morgan for a shorter, tourist/party kind of stay, but perhaps not so much for a longer period or a business trip. Overall, not a bad option at all.
