Some opinions and advices about places to stay in Dublin:

"Dublin city centre is quite compact and as you're on a budget I recommend you get a map and just walk around. The hop on hop off buses might be good value for you too. I'd recommend Kilmainham Gaol, Trinity College, Chester Beaty Library, National Archaeology Museum - the last 2 have free entry; Trinity is free to walk around but imho it's worth paying in to see the Long Room and The Book of Kells."

"Well firstly i'd recommend just walking around the centre of town as the buses are complicated and the city is so compact that there's really no need. if its still sunny you should take a trip on the dart (the train that runs along by the coast) out of the centre to south Dublin. The view from the train is gorgeous and you could stop off in one of the nice seaside towns along the way- Bray, Killiney and Greystones are all lovely."

"Temple Bar can be just what some people are looking for (it is lively and loud), there will be live music in some places, but there are other small areas as well, side streets and all that."

What people says about the best rated hotels in central Dublin. All them says "Ideal location"

The Merrion Hotel: " We were only in Dublin overnight but wanted a central hotel to stay in. Hadn't stayed at the Merrion before but what a fantastic surprise it turned out to be. The service is as good as anywhere I've ever stayed."

Westin Dublin: "Located literally two blocks from temple bar area (all the nightlife) but far enough to be quiet. Walking distance from everything in a great area. Was on a two week backpacking trip through europe and this was our favorite place to stay. Wish we had extended to stay another evening!"

Fitzwilliam Hotel: "Really good location if you wish to stay in the centre of Dublin. The location is super convenient to the tourism office, Grafton street, great restaurants, and all bus stops. Overall, I could not have asked for a better stay!"

The Westbury Hotel Dublin: "The location of this hotel is amazing, your in the center of everything! It cannot be beaten on location. The hotel inside is very impressive, clean and the staff were very helpful. Wonderful place to stay in Dublin."

The Shelbourne: "I stayed at The Shelbourne for new years eve last year. Very well located by st stephens green and all the main areas (o connell street, temple bar, trininty college) are in walking distance. Great Hotel in the best area."

Brooks Hotel: "If you are going to Ireland, definitely stay here! The Brooks hotel had a comfortable luxury that is hard to find when traveling overseas. The hotel is centrally located to a lot of the Dublin attractions. Brooks Hotel, where you should stay in Dublin."

Radisson SAS Royal Hotel: "We stayed in the Radisson Blu Royal Hotel in Dublin in March 2011 over the St. Patrick's Day holiday. The hotel has a great location--it's about a 5-10 minute walk to Temple Bar and Grafton Street; it's in the city center, but it is just far enough away that it's a little quieter. The hotel is situated less than 2 blocks from St. Patrick's cathedral, Dublin Castle, and 2 stops on the Dublin Hop On/Hop Off bus."

Morrison Hotel: "We loved the hotel's location, only a few mins from all the action but blissfully quiet for a good night's sleep. I would certainly recommend and will be coming back to stay. It's the perfect getaway kind of place. Morrisson hotel, is the place where to stay while in Dublin."

O'Callaghan Stephen's Green Hotel: "My husband and I stayed here for one night last week while we were in Dublin. We found it to be a fine stay. The location is pretty good - Stephens Green is right on the edge of city center so it is a quick couple of blocks walk and you're right in the middle of everything. Overall, it was a nice place, good location, and reasonably priced."

Alexander Hotel: "Stayed here with some friends last October. Great location in the centre of Georgian Dublin and close to many tourist attractions including Trinity College and the galleries. Perfect for a short stay in Dublin."
