I'd love to help you find the right accommodation for your upcoming trip next month! :) It is so exciting you'll be spending 5 nights in Dublin. Are you thinking of exploring the area from here?
I've had a look at the self-catering options for Dundrum in Dublin, and unfortunately wasn't able to find any. There is however the 9 Baggot Rath House
in Ballsbridge, which is about a 9 minute drive away, The Cottage
in Kilternan, 12 minutes away, or Canbe-Broc House
in Donnybrook, only 7 minutes from Dundrum.
Would any of these be an option? For more self-catering options in Dublin, take a look here
. If you reach out to them directly they would love to tell you more about the availability and options.
I hope this was helpful, and please don't hesitate to reach out if you need anything else!
