Getting a hotel in Dublin can be a bit tricky. Since it is a small city, its hotels often get booked to capacity fast. Early reservations are a must for travelers and tourists. And booking in advance may prove to be more than just practical. You can also get discounts by reserving a room beforehand.
You will need discounts especially in peak seasons when hotel rates jack up. But there are also reliably cheap hotels in Dublin you can afford even without discounts.
Location plays a great part in the rates of hotels. The closer you are to the heart of the city, the more expensive accommodations become. But before you go ahead and check in at any hotel in the outskirts of Dublin, be reminded that public transportation is hard to come by at night. You may end up spending large sums on transportation that in the end would amount to the savings you got from not staying in a city hotel.
For a backpacker, Dublin's several hostels are your best bet for cheap accommodation. You may have to share a room with complete strangers but it would be fun to meet fellow travelers you can exchange stories with.
If you are traveling with your family or a large group of friends, check out the apartments you can rent for the duration of your visit. There are also bed and breakfast townhouses operated by families. Most of these are certified Family Homes of Ireland (FHOI). This may be the best way to experience Irish living. Their rates may be slightly higher though. Sometimes they can be priced higher than hotels too. So be sure you check the rates first and compare before deciding on your accommodation.
For best rates, book well in advance. And if you do not mind moving your trip, reschedule it during off-peak season. You will get rooms at a much cheaper rate. Also, mid-week accommodations are priced lower than weekends.
