I have put a lot of thought into this post. I have traveled with two other cruise lines (one of them many times) so I can only compare Celebrity with those lines.
It is a lovely ship. I truly believe the crew tries to do whatever they can to make you happy. The ship is spotless.
I am stating what these other cruise lines have, but not the Reflection:
Average. Bed skirt was dirty and stained. Some towels were stained.
