Margaret's place is just as advertised. The room was clean and comfortable. If was the first time we'd booked a room rather than an entire private space, so it was a bit of a new experience, especially with the shared bathroom facilities. Margaret and Gordon were very friendly and helpful. We basically used the place as a crash pad for sleeping as we were very busy on this trip.
The location was good for getting my daughter settled in at DCU. The only additional thing I'd mention is that if you're sensitive to cigarette smoke, you probably would be affected here.
