The apartment was as described and the host was very flexible even allowing us to check in early after coming off an overnight flight.
The apartment would be suited to couples/group of friends who want to have a good time in Dublin. It's not so well suited to a family as it is down a very dodgey alleyway and there is a lot of loud banging at night. I did not feel safe walking my kids down the alleyway once it was dark, and that is 4.30pm in winter.
It is also not suitable for someone with a car. It is €13 to park from 7pm to 8am but if you park for a full day it is €38 ($60AUD) per day.
