The house is a large space plenty enough for large groups up to 15.
The kitchen is well kitted out too so all of you can cook/eat.
All the beds were comfy though you'll need to share the double beds if you want to fit everyone. Not an issue for my group.
You are about a 40minute walk from temple bar so you might find you get taxis a lot into town which cost €20 a pop so does rack up.
Only downside to the place was the water. We had issues when all 3 showers were being used with temperature and water flow. Still, wasn't exactly a huge issue, everyone still managed to get showered everyday.
Conal was a great host too, always answered any questions and even brought round extra sheets for the sofa beds on request.
