Dag Gino,
It's great that you are planning a trip to Dublin. Do you already know what you'd like to see and do in the city?
In order to find accessible accommodation, I'd suggest filtering the search results by ticking "Wheelchair accessible" (or equivalent option) on the accommodation platforms. You can do so on
B&B Ireland and
Let's Go Self Catering for instance.
Our
accommodation search tool is also a good place to start looking for places to stay in Dublin, although you'll have to click on the listing to check whether they are wheelchair friendly.
Here are also some helpful
threads and
pages on accessibility in Ireland to help you plan your trip.
Groet,
Antoine
