I totally recommend this apartment - right in Dingle Town so walking around (we were two friends with one car) was easy. It's a lovely space and just right for two people or two adults and a child. We were greeted by one of the owners of the shop downstairs who gave us a quick show-around - for which you need to come before shop closing hours. They left us milk, juice and Irish brown bread for breakfast which we appreciated, and there were a few staples there as well.
The wi-fi worked well and was very appreciated as many cafes say they have wi-fi but the reality is sketchy ...
The only problem was recurring, but they tried to address it during shop hours, and they said via text that they'd never had it happen before. When we got there the shower had no water pressure - so we couldn't shower til the next day. The problem recurred two days later, and again, no fix til the next day and then the water was either extremely hot or freezing cold and then the pressure disappeared again. Again because it was after shop hours we couldn't reach anyone and finally gave up on showering. So - you might want to check with the owners re: this, and always check the pressure/temperature before closing time, as well as whether there's a way to reach them afterwards other than text/e-mail.

Check with the owners of the two music stores if you want to hear Irish trad music - they will know who's playing where/when and the owner of the larger store hosts concerts three nights a week.
