Malachy was super helpful every step of the way. He waited for us when our plane was delayed and even prepared lists of attractions and amenities (supermarkets, restaurants etc.) in the vicinity.
The house was nice. Comfortable furniture, very clean throughout, and with modern appliances.
The area is quiet. We slept well every night. I'm pointing this out because a lot of reviews for places in the Temple Bar area mention a lot of noise and even being supplied by ear plugs on arrival. That was not a problem here. There was no loud external noise any of the four nights (Sunday to Wednesday) that we were at Malachy's place.
In summary I would heartily recommend Malachy as a host and would definitely book this house if I ever had to return to Dublin.
