, like all capital cities, is expensive...and what is 'affordable' for one person may be ouside the budget of another.
I haven't stayed in that particular area of the city but I'd check rates & reviews for e.g. the Drury Court
on Stephen Street Upper
, the Travelodge
on Mercer Street Lower
, the Dawson
on Dawson St
, the Central
on Drury Street
and several others around Iveagh Gardens
hotel chain is well-established in both Ireland and the UK and offers clean, comfortable accomm at decent rates so I'd check that first and use it as a baseline to set against other options.
I strongly suggest you look at rates & reviews for all the above on the long-established and reliable www.booking.com
It has excellent mapping and good rates but...most importantly for me...its reviews can only
be posted by people who have booked through the site and completed their stay.
