We had a great time staying at Jo's place. Perfect size for two couples, with comfortable double beds, clean bathroom and everything you may need (plenty of towels, guides of the city, take-away menus…)
Jo was very responsive and it was easy to arrange the booking and check in / check out. She also gave us very helpful tips for our first night out to experience Dublin as a “local”.
The place is walking distance to the city centre and the Guinness Storehouse. Otherwise, a cab would cost you around EUR 8 (for 4). All in all, highly recommended.
