Old humanist seen around in Hotel Oceania (5)

'old humanist' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'around in hotel oceania' is the wordplay.
'around' says the letters should be written backwards.
'in' says the answer is hidden in the clue.
'teloc' can be found hidden inside 'hotel oceania'.
'teloc' written backwards gives 'COLET'.

'seen' is the link.

Can you help me to learn more?
