As others have pointed out, you need to climb a lot of steps to get up to the entrance Oratory. By way of immediate compensation, the view back down of the grounds is quite beautiful. For me, the most rewarding part of the experience was the stained glass, which uses almost an Art Moderne approach to the figures that is quite unique in my experience. This is carried over to the wonderful ironwork that is found in various parts of the sanctuary.
The altar area is perhaps less ornate than one would expect, but I found it wholly in keeping with the tone established by the figures portrayed in the windows and the metalwork. In addition, the carved wood figures are especially graceful and add to the sense of an unusual aesthetic vision for the building as a whole.
As might be expected, the ambient lighting is quite low and so be prepared to take extra care to use appropriate settings on your camera. In my case, I found that some digital enhancement provided a more true to life representation of what I saw in many pictures.
While not Catholic, it was easy to feel the spiritual nature of the Oratory and I encourage those of all faiths to see this distinctive attraction.
