I booked this room for a few days of sightseeing and museums and found it very well suited to my needs. The room matches the advert and is both comfortable and stocked with all the amenities you could want (likewise the associated bathroom and kitchen). The place is well connected, it was about 15 minutes walk from the centre and felt both easy to get to/from and in a safe-feeling neighborhood.
Bob was a very welcoming host from booking to checking-in. I didn't have any need to contact Bob about the place after check-in but I was left with every impression that had I had to do so then it wouldn't have been a problem.
Overall I'd highly recommend the room for a short stay in Dublin.
