Hotel Riu Plaza The Gresham Dublin

Hotel Riu Plaza The Gresham Dublin

8/10 Good
"The RIU Gresham Dublin is a well appointed hotel in the Dublin 1 area. Its location makes it convenient to shopping along Henry St, seeing sites like the GPO, St Marys Cathedral, Hop on Bus, Temple Bar etc. A bit longer walk will take you to Trinity, Jameson etc. Lots of restaurants nearby. The staff was very friendly/accommodating and the breakfast buffet satisfying. I don’t know that I would pay 25€ per person for it but it was included in our particular fare."

Frequently asked questions

How much does a budget hotel in Castleknock cost?
Budget hotel prices in Castleknock vary, but you can find a great deal from £90 on Expedia. To find the cheapest budget hotels, be flexible with your dates—typically, off-peak and mid-week stays are cheaper. Stretch your budget further by looking for hotels with free breakfast, free parking or free airport shuttles. Sort your search results by "Price: low to high" to see our lowest rates.
Which area of Castleknock is best to stay in for cheap hotels?
For budget-conscious travellers looking for affordable accommodation in Castleknock, focusing on areas slightly outside the immediate village centre, such as those closer to Blanchardstown or along major transport routes, will yield the best value. Castleknock itself is quite a desirable residential area, and while charming, its accommodation options tend to be more upscale.

Solo travellers might find better deals in hotels or guesthouses located a short bus ride away, perhaps nearer to Connolly Hospital or along the Navan Road. These spots often have more competitive pricing and still offer good public transport links into Castleknock village and further into Dublin city centre. Look for places with easy access to bus routes like the 37 or 38.

Families seeking value should consider properties that are a little further out, towards Blanchardstown, where there might be larger chain hotels offering family rooms at more attractive rates. This area also provides access to amenities like shopping centres and parks, which can be convenient for families, and it's well-connected by bus to Castleknock and the wider Dublin area.
How can I save on a budget hotel in Castleknock with Expedia?
There are plenty of ways to save on a budget hotel in Castleknock. Join One Key™, our free travel rewards programme, to unlock Member Prices across a range of hotels. Typically, booking in advance will help you save on hotel bookings. If you're feeling spontaneous, be sure to check for last-minute deals.
What free activities should we do in Castleknock?
For budget-conscious solo travellers visiting Castleknock, there are several rewarding free activities to enjoy, primarily focused on the area's natural beauty and historical charm. The Phoenix Park, one of Europe's largest enclosed urban parks, is right on Castleknock's doorstep and offers a wealth of free exploration.

Solo travellers can spend hours walking or cycling the park's extensive network of roads and paths, keeping an eye out for the wild fallow deer that roam freely. Within the park, you can visit Áras an Uachtaráin (the official residence of the President of Ireland) from the exterior, and explore the historic Magazine Fort or the Wellington Monument, all without an entry fee. It's a wonderful place for a peaceful stroll or a vigorous walk, providing a refreshing escape from urban life.

Another excellent free option is to wander through the village of Castleknock itself. While smaller than some other Dublin suburbs, it has a pleasant, historic feel with its old church and village green. You can enjoy window shopping, soak in the local atmosphere, and simply take a leisurely walk around the area, perhaps stopping for a picnic in a park or enjoying the scenery along the Royal Canal Way, which runs nearby and offers scenic paths great for walking or jogging.
Is it cheaper to book flights and a hotel in Castleknock as a package?
Booking a hotel and flight package on Expedia can be cheaper than booking flights and hotels separately. Bundling can lead to significant savings, especially for international travel or when booking well in advance. However, savings vary depending on factors like destination, travel dates, and availability, so it's wise to compare options. With access to over 300,000 hotels worldwide, Expedia makes it easy to build the perfect travel package.
Can I cancel my budget hotel reservation on Expedia?
Many Expedia hotel reservations are refundable, provided that you cancel before the hotel's cancellation deadline. This is often within 24-48 hours of your scheduled arrival. Be sure to check your booking confirmation for the exact cancellation policy. For maximum flexibility, use Expedia's "Fully refundable property" filter during your search to find the right budget hotel in Castleknock for you.
