Trish was a lovely, kind and thoughtful host. Her AirBnB has a single bed upstairs in a classic Dublin house, in a safe, generally quiet neighbourhood, not yet gentrified.
It is walking distance to the Connolly train station and the intercity bus station, Liffey River (about 20 minutes, depending how fast you walk), a bit further to Temple Bar, and on a bus route for those not keen on walking. It was modestly priced, clean, and had great WiFi. Note that there are stairs which you will need to be able to carry your luggage up. I loved my stay there, and would stay again if I returned to Dublin.
