You should be refunded in full for days paid from when you were illegally evicted also reimbursement of STG10 for luggage storage as she did not honour check-in time.

She had no right to enter your room and would require photographic proof of her complaint of ‘bad condition’, a before and after shots and date stamped same as the toilet.

Your husband’s episode was beyond his control and deserves sympathy and understanding.

I would demand replacement of his missing blood testing kit from her or you’ll file a report with the police for theft and trespass in order to claim insurance. I would even expect compensation for added expense and inconvenience of the illegal eviction as well as adjustment for a small room advertised as large.

Seek advice from a local Citizen’s Advice Bureau in Edinburgh.

I’d very much recommend making an issue of it, cause trouble, informing her you are quite prepared to escalate the matter to police for theft and trespass, the advertising standards authority, the agent AirBnB, and the local court if your claim is not settled promptly. I’d expect from reading your report that you’d have the sympathy of the court and the police. Be polite but firm and just state the facts.
Good luck!
