Let me begin by saying that this is a clean place with internet access and a great location.
With that said, I have a couple of complaints. First, it appears there is a second room being rented out and the townhouse is renter-occupied rather than owner-occupied. I don't mind this, but wish I had been told because it certainly would have prompted me to lock the room. Instead, we had someone come in the room late the first night looking for their bed, which is scary when you assume everyone else in the house knows where they're supposed to be.
Second, noise was an issue. On the first night, a Sunday, noise from upstairs started around 3am and went on for well over an hour. During that time it was impossible to sleep. Then, during the following two days, a Monday and Tuesday, heavy stepping and conversation were carrying on directly above the room beginning around 6:30am. After that, sleep was a lost cause. As great a city as Dublin is, it's hard to enjoy a place where you can't sleep. This felt like an overpriced hostel rather than an inexpensive hotel, and it certainly didn't feel like staying in someone's home (though I acknowledge that wasn't the intent with this Airbnb).
