The Sunny Barger is a fun and unique experience, one we would repeat if we were to return to Dublin. It is well situated near a great market and quite a few restaurants, and within a decent walking distance to the heart of the Dublin attractions.
Keep in mind though that it is a boat with all of the charms that go with living on a boat. But I would highly recommend it as a fun alternative to your traditional Airbnb stay. Tom and his associates were wonderful, being both very responsive and very helpful.
