This was a decent, basic apartment in the north of Dublin. It was fairly spacious and had a lot of light. There were good amenities around -- Tesco & butchers across the street, bus stop right outside, train station two blocks away -- and it was a quick trip to the airport. It's about a 25-30 minute walk downtown from the apartment, and also about 20 minutes to sights in the north like the Botanic Gardens, so it's well situated if you want to access sights around Dublin. Communication was quick -- we had an issue with a leak under the sink and they sent a plumber over immediately.
What other reviewers have said is all true. Some things that were particularly noticeable during a 4-day stay in summer: Blinds but no curtains on the windows (the blinds let in a lot of light early in the morning in summer, so bring an eye mask). There is a lot of street noise, even with the windows closed, and in summer you need to keep the windows open because the apartment gets quite warm and there are no fans. With earplugs and closed windows at night, it's manageable. Also, check in was not as easy as many other Airbnbs: There's no key box and you don't meet at a set time -- they gave us a window of 30 min and arrived right at the end of that window. The itinerary doesn't give the house number so it wasn't easy to find (but they were quick to respond with directions when I asked).
