Perhaps the best hosts I've ever had, and I've done quite a bit of travel on Airbnb. Host is very thoughtful and interested in making a guest comfortable, working quickly to remedy any issues.
The apartment is a short walk to transportation (3-8 minutes), but you can get around all of central Dublin just by walking.
There's construction going on behind the unit, but they don't start until late morning and they quit early evening.
Water pressure is good and hot water is plentiful.
Wifi is fast and stable.
Floors seem thin, so I heard a lot from above and below the unit. The other tenants are quiet, but they will come in at 3 AM and you can hear them using the toilet and moving around. I'm a light sleeper and didn't have much of a problem, though.
Kitchen is well supplied, though the only hot water in the unit is in the shower, I think.
Laundry machines are coin operated (2 euro coins only) and shared with other tenants. Someone put a wrong coin in the washer and caused it to not work, but host was very fast in cleaning out the coin and getting it working again. No contention issues with using the facilities with so few people living in the complex.
Groceries are 10-15 minutes away, which is handy enough. Lots of places deliver to the area as well.
I really enjoyed my stay and would recommend the apartment.
