My friends and I visited Dublin to see a show at Vicar Street, and chose this apartment because it's within 10 mins walking distance.
This apartment is slightly outside of the centre of Dublin but is conveniently located opposite a bus stop with regular buses right into the heart of the city. It was very clean and comfortable with a particularly nice bathroom. There's a small supermarket a few doors down if you're planning on self-catering and a nice coffee shop very close by as well.
The apartment is extremely convenient if you want to visit the Guinness storehouse.
I'd definitely choose this apartment again if visiting Dublin again in the future, the hosts were great communicators and were kind enough to provide some tips for what to see locally.
