My Grandma and I stayed with Conor for three nights as we wanted to explore the Howth peninsula. He gave us the warmest of welcomes! He picked us up from the busstop upon arrival and, for a small fee, even arranged to drop me off and bring my Gran (who doesn't speek English) to the airport when we checked out - this saved us a lot of time and stress and it worked out beautifully. The room was nice and tidy and had plenty of room to put our stuff. I had lovely chats with Conor and his wife but they also gave us enough privacy in the evenings to relax. Their dog Nina is probably the most well behaved dog I have ever met, very calm and friendly.
The only thing I would maybe adress is that if you are a very clean person, you should be aware that there is a shared bathroom. It was okay to use, just if you are picky about these kind of things, be prepared that it won't be absolutely spotless at all times.
If you are looking for an affordable cozy place to stay in a wonderful calm area near beautiful hiking spots and with a warm and welcoming atmosphere - this is the place to be!
