It's worth recommending. The room is very new. The breakfast is delicious. The service staff are very good. It's just that the UnionPay card in the hotel cannot be used by the machine. It's next to the river. There is a supermarket and a restaurant next door. The slippers are also very good and very soft

The Merrion is a Hallmark of service and sheer quality. We arrived to be greeted by a friendly concierge and the news that our room had been upgraded to a junior suite. Lunch in the Cellar bar was an absolute joy and friendly, well clued in staff made the experience more special. The room was fabulous, with every comfort you could imagine. The bed was so comfortable, as were the couches.I cannot speak too highly about the service at this wonderful hotel.

The room is spacious and bright. The location is very safe in the embassy area. For food, there are some restaurants about 5-8 minutes walk away. Although there are not many choices, it is okay to eat. The hotel's afternoon tea is very ordinary and has no special features. It feels very comfortable and quiet to live in. I will probably stay in this hotel again next time. The Christmas atmosphere is also very good.

Second time staying in this hotel. The location is South of the river but only 15mins walk to most tourist attractions, Guinness Storehouse, Dubhlinn Gardens and Temple Bar. The hotel is clean with plenty of staff to assist and breakfast is plentiful. Can be busy on a weekend but that is like any hotel in Dublin City Centre. The hotel is just round the corner from the Aircoach bus stop for travel to and from the airport.

Amazing First Hostel Experience – Highly Recommend! I had never stayed in a hostel before, so I wasn’t sure what to expect—but my stay at Generator Dublin completely exceeded all my expectations. From the moment I arrived, the atmosphere was welcoming and comforting. The dorms were clean and well-maintained, and I was especially impressed with how spotless the bathrooms and toilets were. They even provide hair dryers, which is such a thoughtful touch. The staff were incredibly friendly and helpful throughout my stay—special shoutout to Alex, who was always kind and approachable. The vibe downstairs was super fun and lively. Even if you don’t have plans for the evening, there’s plenty to do right at the hostel—games, live music, and a party-like atmosphere that makes it easy to meet people and just enjoy the night. I was also lucky to have great dorm mates, which made the stay even more enjoyable. All in all, staying at Generator Dublin as my first hostel experience was truly memorable and amazing. I’d absolutely recommend it to anyone looking for a comfortable, clean, and social place to stay in Dublin.

I was impresssed by the friendly welcome I was given at reception. Although I knew I couldn't book in till 2pm, I went early in the hope of them looking after my case. Not only do they do this for no extra charge but I was allowed into my room at 11.30am as it had been vacated. The hotel is in an excellent location for sightseeing as Christchurch and St Patrick's Cathedral are within 5 mins' walk and Dublin Castle and the Esther Beatty exhibition, which is not to be missed, is just round the corner. The room facilities were excellent with air conditioning unit, fridge, safe, coffee and tea making equipment, an iron and hairdryer and of course constant hot water for a shower. Downstairs there was a restaurant and bar available with music in the evening, which stopped at a reasonable time. Breakfast was also served in the morning, simple but enough. It was well worth the price charged simply because of its location.

There is no commercial facilities around the hotel, but there is a golf course nearby. There is a park about 500 meters away. The environment is beautiful, comfortable, pleasant and very quiet. The hotel breakfast is very rich and the coffee tastes good. The gym is well-equipped and the swimming pool is clean. The room is clean and tidy, with bottled water. The front desk service attitude is good, and the restaurant service is warm, thoughtful and meticulous. I will definitely stay here next time.

Stayed at the Bonnington Hotel and was greeted well but I was expecting a fridge in my room as the advert clearly states that a fridge would be available but I didn’t get one and after requesting several times I still didn’t get one. The parking attendant is also very rude and seems to be on the look out to cause issues for visitors. The parking was very busy and spaces are limited, be prepared to walk around the side of the hotel. BE WARNED OF THIS GUY!!

This didn't make sense. I've been staying here for years but this is the first time I've come across this situation. So if the room is ready, you can check in early. Everything else was great.
