Queen's accommodation in Taipei, fairly regularly visited (6)
I believe the answer is:
apiary
'queen's accommodation' is the definition.
(an apiary is an enclosure for bees - eg queen bees)
'taipei fairly regularly visited' is the wordplay.
'regularly visited' indicates alternate letters (letters are taken at regular intervals).
'taipei'+'fairly'='taipeifairly'
The alternate letters of 'taipeifairly' are 'APIARY'.
'in' acts as a link.
(Other definitions for apiary that I've seen before include "Collection of beehives" , "Colony giving off a buzz?" , "A place for bee-hives" , "Place to keep bees" , "Place where bees are kept for profit" .)
