GL with finding the true torch-bearer to replace Sandra.
There are a couple of other profiles in the same area which may also be working that flat (given it had 3 rooms) which do look decidedly ropey and may have poor feedback.
TBH if it's all the same receptionist then I don't think I CBA to find out...
Sadly every attempt to contact Sandra via WhatsApp on the number she assured me was hers have gone unanswered
