We stayed at the Hilton in Kilmainham for 3 nights in January, Got to say didnt expect much, having stayed in Hilton Hotels before, but this one really stands out, The room was fantastic it was spotless and very large, the bathroom had both a bath and shower, that knocked you over if you wanted it too, We ate There as well, the food was excellent with a varied menu, and the prices were very reasonable, If I did have one grumble it was the breakfast was abit on the cold side, but only on the first morning. The hotel is situated about 3kms from city centre, but the Luas (tram system) is only a 10 min walk from hotel, and the Pub opposite was without doubt the friendliest I have been too. I will be returning to this hotel again.

This hotel is just a great place to say on a business trip. Service is excellent, food (well only breakfast tested) is just what I can expect to start nicely a day (quality, real fruit juice, good bacon and eggs - just the coffee, with is still an English coffee... would be good to offer some espresso for international travelers ;-)

Price is great (paid only 100 GBP that day).

Gym is a real one, large, lots of people actively working their body here ;-)

Will surely keep this address for my next stay in Dublin.

We booked and paid 4 days because we expected to get the usual Hilton-service level as we had in the past in other cities. The reception staff and the welcome were ok but not really want we expected. The worse experience was in the Hotel bar: we waited 15 minutes and nobody took an order, after this wasted time we asked twice the bartender and he shouted "you need to take your orders with somebody else, I am not in charge for your table". This is a civil servant mentality and not the behaviour of a 4 star staff member.
Location of the Hotel is not really in the center, so you need everytime a taxy to get in and out.
The wellness-area is not up to date, smells bad and the 2 saunas are not worth to enter.
Positive is the breakfast and the rooms (even though there is no ventilation in the bathroom).

I've stayed there two weeks in late november 2012.
The hotel is 2.5km from the city centre, which is quite a long stroll to take on foot; fortunately, while pricey, dublin bus comes to a help, with many buses to and from the centre.
The hotel building is nice and new, in a new development. The corridors smells kind of funny, but the rooms are odorless.
The room we had were very large, with a decent sized desk which could fit two laptops with two people. The beds are king sized, a nice extra since irish have smaller beds than the continental people. The bath is new and looks like a prebuilt unit from Italy, shipped and placed.
Other facilities includes a business room, a mini-welness gym and a small SPA, which is really a hydromax and a sauna.
The breakfast is quite rich on the salty side, but is somewhat poor in the sweet/continental side.
The wi-fi in the hotel room is really abysmal: it's cappet at 30kbps, a speed that you would have been deemed acceptable 20 years ago. Talking to the manager, it seems that they are working to replace the connection, so it could be better in a short while.
