You rarely get something that is better than in the pictures, but in this case it definitely applies. The house is lovely, room is clean and the bed is comfortable, the shower is nice, and the kitchen is well equipped. Wifi was reliable and fast too. Damien is the loveliest host ever, and assisted us with everything (including using his own car). He really goes out of his way to provide the best Airbnb experience, and it was a pleasure to meet a host like him who really cares about his guests.
Getting to the sights by bus was easy too, it takes round about 10 minutes to the Guinness Storehouse and ca. 15 minutes to Trinity College (as examples for some points of interest). It's about 20 minutes walking to Heuston railway station. Book it, you won't regret it! We were truly sad we couldn't stay longer and are already trying to return asap :-)
