For me, both appearance and service must meet a minimum threshold, otherwise the whole experience falls into the 'negative'.
I had experienced both amazing beauty, and amazing service. It is quite rare if not impossible to get a '10' in both though.
In the end, what I remembered most fondly are the meets that leans towards great experiences - it's the 'feeling' that I remember most, less so with the 'sights', if that make sense.
