We spent four days at Marta and Roberto's flat and we enjoyed the place very much. Roberto and Marta were very hospitable and made us feel at home. The room and the bathroom were very clean and well equipped. No TV in the room but we were not interested in that. Our only concern was that the walls are pretty thin and noises can be heard from one room to another.
The location is very convenient and most of the interesting places can be reached easily walking. Plenty of pubs, bars, market and stores nearby, and it is a just a few minutes from the General Post Office (GPO), one of the most remarkable places in 1916 Easter Rising. We highly recommend staying at Marta and Roberto's.
