Christian's place is conveniently located and a decent size. We stayed here on our last night in Dublin and it was fine for one night. It would be uncomfortable for more than that. There were only two towels for three people and the shower ceiling appeared to have mold. I didn't reach out during our stay as we were only there one night, but I'm sure he would've been responsive. He was always quick to respond during the booking process and had left his contact info for us on a whiteboard in the apartment.
