Hi D&G,
I saw you weren't getting any replies so I thought I'd reply.
My brother went in last year for shoulder surgery (his surgeon also worked out of Blackrock Clinic). I visited him and was very impressed with the set up, very modern and high tech, each bed had it's own adjustable TV etc. The hospital itself was very quiet - I don't know how they stay in business.
Regarding his care, he had no complaints and was well looked after and he even enjoyed the food!
If you have any specific questions I'll ask him.
Hope this helps.
