I stayed at this hotel for a week in December, and was extremely happy with the stay. First, the location is phenomenal - just across the street from the back of Trinity College and less than a 10 minute walk to Temple Bar, Grafton Street, Henry Street, Merrion Square, etc. For being in such a central location, I was happy to discover that the actual street it's on (Pearse) is actually very quiet and so you don't get the street or pedestrian noise at night that you would in other nearby locations. Literally 30 seconds around the corner is an Ulster Bank ATM, a SPAR (convenience store) with a deli and coffee shop inside.
Second, the hotel itself is super funky with a fun and unique lounge, cool bar, and large restaurant area. There is also a courtyard - obviously closed when I was there - that is inexplicably full of random animal and cacti statues. The hotel offers a variety of room types and is actually fairly large but feels like a small boutique hotel. The breakfast buffet is decent but not amazing, and costs 12 euro which is, like pretty much every hotel in Europe, ridiculous, but I've seen worse. There is free wifi in all the rooms and public areas, hairdryer and nice toiletries in the bathrooms, and a a fair selection of channels on flat screen televisions. The bathrooms are a good size for a European hotel as well, which was appreciated. I didn't have too much interaction with the staff, but what I did have was very pleasant.
The only (very minor) complaints I have are that the lighting in the rooms isn't so great, so if it's dark outside the only place you can properly see yourself is in the bathroom. Also, within the hotel there are four different "groups" of rooms - Trinity, Tara, Courtyard, and Georgian. The Trinity and Tara rooms are accessed by the elevator immediately next to reception. I stayed in room 406 my first night, when I was by myself, which is a single room. This room seemed fine, but when I moved to a double room, which I was sharing with a friend, we were in a Courtyard room which was MUCH nicer - cleaner, more modern, and better decor. The Courtyard rooms are accessed via a locked door past the lounge and then up a separate elevator bank. I never did figure out exactly where the Georgian rooms (suites) were, but the photos certainly looked nice.
In sum, I would not hesitate to recommend this hotel to anyone!
