We had a great stay at Peter's place. Location was fantastic, right in the middle of everything. Peter was super informative and had a lot of advice to share about Dublin.
We chose Peter's place specifically to have a little more room and so we could do laundry. Everything worked out great in that respect. The apartment was very comfortable.
Check in was a little difficult as we had to contact Viny (great guy by the way) and it can be hard to text people when you're traveling in another country. But as long as you're able to reach out and give him your arrival time, you should be fine.
