I can just repeat what others said before! Had a lovely short stay at Bob's place - got detailed directions in advance, recommendations on things to see & do in and around dublin when I arrived, check-in/check-out were relaxed, communication really nice.
The room is 'klein, aber fein' as we'd put it, the shared bathroom
worked out okay with 3-4 other guests, the kitchen even includes a dishwasher, breakfast cereals were provided (maybe ask Bob if you're allergic to nuts or anything as labels may not always be up to date).
The only thing from the property descripton that I missed was the cat ;)
