This one is a reliable bloomer for me, but usually only has one flower per spike. I was once told this should be sequential, but the spike always dies back after the first flower (one spike managed two flowers last year).
It has two spikes as it did last year, but this is the first to open a flower.
This year I've not moved it when it started blooming. In the past I've moved it to the living room, but I've left it in the usual spot on the landing in the hope it will be able to carry on producing flowers on the spike.
I love this one even if I only get one flower each time. It has a faint citrus fragrance.
