My mum and I had a great stay at John and Caroline's. They were very kind and welcoming and ready to help out with any questions or problems you might have. Their house is about 20 minutes away from Dublin City centre with the bus so it's easily reachable with public transport. You can use their kitchen whenever you like and although it is their house they give you enough privacy to do your own thing but they also don't mind inviting you to their sitting room to watch TV together and have a chat. At first we were a bit apprehensive about having to share the bathroom with all the guests staying at the house but I can safely say that there were no problems at all and the bathroom was absolutely spotless as they cleaned it every day. John and Caroline were also kind enough to welcome our small dog into their home and he had a great time playing with their lovely collie JD. John picked us up from the airport and took my mum back for a very reasonable fee so you won't have to find a taxi or use public transport with all your luggage.
This was the first time I (and my mum) ever used airbnb and John and Caroline only started a few weeks ago but the experience with them was so positive that I would gladly stay with them again!
If you're looking for a good place to stay with easy access to Dublin but not the hustle and bustle of being in the middle of a big city and staying in a nice, welcoming family home with very kind people I would definitely recommend staying here!
