I would highly recommend Aline's apartment. Aline and her family were very nice and good host. The room has everything you may need. We stayed there only for a night but wished it was longer.
The flexible check in is definitely a plus as we were able to drop off our luggage early during the day and enjoy most of our trip free of any weight. The bed is very comfortable.
The apartment is clean and the location is great. The hosts are very welcoming and make you feel at home. We will definitely go back when visiting Dublin.
