The apartment is specifically designed for short stays and immaculately presented and clean. If you have a car, plan ahead as the park closet to the apartment is 20euro a day while there is another car park 10m away for 5e a day.
Furthermore, depending on what number apartment your getting you'll need to climb a lot of stairs. My apartment was number 4 and that was four flights of stairs.
I'm conclusion, it's spotless clean, it's not a lived in apartment but designed specifically for short stays. There won't be a homely feel to the place but that shouldn't stop you from enjoying Galway city on any occasion.
