If you need a fuss free and perfectly located pit stop in Dublin, you'd be pressed to find anything better than Sam's place. The location can hardly be beaten and you probably won't need to use much public transport at all in order to enjoy all that Dublin has to offer. There are plenty of shops and lovely food places a few steps from the house.
Check in is extremely easy: expect a lot of stairs so plan accordingly if you have trouble carrying a lot of bags! The room is clean and cozy, and there's plenty of privacy with a hallway straight to the room from the front door. Cats are adorable and polite. Bathroom was always spotless and we hardly felt like we were sharing it. Both our hosts were extremely nice and friendly.
