We were a couple of friends who stayed in this apartment. As most of us were architects, we really appreciated the detail and design. Wow! It was really spectacular, and such a unique experience.
We were however 6 guests, and the 5th and 6th bed, were really only camping cots. I think the apartment should rather be advertised as a 4 sleeper, as the camping beds are really not comfortable nor suitable to sleep on.
But next time we are in Dublin, and we are 4 or less guests, we'd love to stay there again, as it's perfect for 2-4 people.
