We stayed for 3 days over Christmas in Donal's and Carmel's appartment and were really happy.
Donal and Carmel were excellent hosts, gave us a helpful introduction to Ennis and had great tips for our time in their appartment. They like to travel and are using airbnb's during their travels, which you definitely perceive in the facilities of their appartment
The appartment is situated in the heart of Ennis, in the middle of nice old town streets. It's a two floor appartment, with 2 bedrooms on first floor and a living room with kitchenette on second floor. For us as a couple it was great, but for more than 2 people, the living room may be a little bit narrow.
