We booked 2 rooms at the Fitzwilliam for our stay in Oct 2012. (3 nights)
Staff were really friendly at check in and concierge was also helpful with tips for our time in Dublin.
I was very pleased with the rooms, one of which had a balcony that overlooked the park - it was nice to sit out there and watch the world go by. The rooms were spacious and stylish, bathrooms also very nice and newly decorated.
Location was fantastic. Right on the to of Grafton St, and opposite the park. We strolled through the park many times, it was lovely.
Did not eat at the hotel, so cant comment on that.
Would stay here again and would reccomend to friends.

The Fitzwilliam is in the middle of Dublin across from St Stephens green. I had a queen room with a balcony overlooking the green. I highly recommend the balcony rooms. The staff was helpful and friendly.

We staying at the Fitzwilliam hotel in late October, having read numerous reviews. We were not disappointed. Interior was very modern, and clean, overall very boutique style. Our room was on the fifth floor and located not far from the lifts. Our balcony was overlooking St Stephens green, which was fantastic, this was an upgraded room - which I would definitely recommend. Had the weather been better we would definitely have used the patio heater and seats relaxed. Rooms were very well equipped with the usual mini bar, tea / coffee, and luxurious bathroom. Little extra touches were an umbrella and stereo.
Location is perfect with hotel situated just at the top of Grafton Street, close to shops, restaurants and tram.
When we arrived, concierge parked our car for us and again when leaving, they went and brought it round to the front of the hotel, as it was pouring with rain.
Buffet breakfast was one of the best I have seen which included the usual sausage, eggs, bacon, but also cheese platter, smoked salmon, pastries and fruit.
Out of all the hotels I have stayed in Dublin this is by far my favourite, because of location and standard of the hotel.
A really enjayable stay, and I will definitely be back - I cannot recommend this highly enough.

Stayed in this hotel just one night on a business trip. The room was really cosy, with a super comfy bed and very spacious bathroom. The hotel is ideally located near the commercial streets of Dublin and there is plenty of restaurants around the hotel. The rooms with the view on the large park are very nice and not very noisy despite being over the street.
