We really loved this place. It looks exactly like it does in the pictures, and the hosts were super-friendly, welcoming, responsive and helpful. It's also great because it had a washer and dryer (but no dishwasher.) It's very close to the super pretty town of dalkey, which had a great health food store / Cafe where we were able to get some vegan food and a bunch of other shops, restaurants and pubs. It was also really close to a lot of places that we wanted to visit along the coast.
The only downsides were not really specific to the host, but more just something that you encounter in Ireland in some people's homes. The water for showers is only warm in the morning and evenings, but even when it is on it doesn't seem to be warm for very long. I wasn't even in the shower for 5 minutes one evening before the water was absolutely freezing.
Also, we found ourselves getting cold because the heating is turned off in the house at night even though it was winter. However, there was a space heater that we were able to use and so we made do.
