I am normally very hesitant about staying in an Air bnb that has other people in it, always opting for the entire place option, however hotels reaching up to £300 for the Metallica at Slane Castle show meant I had to go with an occupied Air Bnb and honestly, if I ever visit Dublin again I would choose to go with Trish over any hotel or empty air bnb. she was really helpful before I even arrived (checking to see I booked my bus to the gig because she saw they were selling out), we were constant communication before and during my stay. The house itself was just a short walk from town, it was clean, I had access to a private bathroom, it was in a safe location and as I am quite tall, she even made provisions for a double bed rather than the standard single option. Trish went above and beyond what you would expect from an air bnb, even offering to pick me up at 1am after my gig, as well as dropping me off at the airport the next day too.
Highly recommend if you want a cheap, clean, comfortable and friendly stay in a city that is notoriously expensive
