We had a great time in Dublin staying at Nour's. The room is a little small but there is plenty of storage and you will be only staying the night there anyways because there is so much to do. It is not in the centre, but there are several bus stops really close to the house, which take you directly to the centre. We bought a 72hours bus ticket for only 35 euro, which includes all public transport and hop on hop off tours. There are a lidl and tesco close by, which is super handy as well. All in all, would definitely recommend staying with Nour and his super friendly girlfriend.
