The studio is full of light and it is conveniently located. The host has a well organized procedure for the check-in. A few things can be easily improved: a better mattress (you can feel the spring coils) and a properly sized towel for the shower. The washbasin is very small and it is normal to spill water on the floor. Kitchencorner has everything you need. To sum up: good value with few improvement opportunities.
For exploring Dublin, the apartment couldn't have been better located. The bus to and from the city centre stopped half a block away going and right across the street coming back, and within three blocks was a Tesco supermarket with a pharmacy on one side and a good butcher, selling some prepared entrees, on the other.
The bay window provided lots of light and a sweeping view of Dublin and the green hills beyond. Almost everything we could have wanted for self-catering was shoe-horned into the tiny kitchen alcove. And the flat was indeed tiny, even for a studio. Because we had to pull the bed down out of the wall, we couldn't get from the kitchen area to the little table by the window until we'd made it up and stowed it. (There were no bedside reading lights, so anyone liking to read himself or herself to sleep should bring e-books on a tablet.) Also, there were a number of small flaws that, added up, detracteed from our comfort -- things like no towel racks in the bathroom and Laytex gloves used to stop holes in the shower ceiling. We were all too aware of the cranky baby nextdoor. Because the owners live an hour away and there's no on-site manager, we were unable to get the fixable issues corrected. But if you're flexible and prepared, this may be the self-catering option for you.
