So this was unfortunately very disappointing. My host wasn't there to meet me but asked a friend to greet me and she was late and so I was left hanging outside the building for quite some time . I tried calling Sarah and left voice mail and also tried to call the friend of the host who also didn't answer. When she arrived she apologized for being late and told me that the number I was given wasn't even her number!
She showed me in to the apartment and left 30 seconds later as she was in a rush .
Whilst the location was great and ideal for my needs as I was attending a local training event ,The apartment was in dyer need of cleaning. The shower and the toilets were not fit for purpose. The room was untidy and the bed was obviously not cleaned of the sheets changed from the last occupier. They were filthy.
The window was jammed open but Sarah has since told me that there was a method to close it that I wasn't made aware of but no instruction left or advised by her host.
I was advised that the apartment was left empty and that i would be the only person in it for the weekend. When I returned to the apartment two hours later I found it was occupied and that this lady had no idea that it had been let through AirBnB. This was the last call and so I left the keys in the hall and politely asked the lady to tell Sarah that I could and would not be staying in her apartment .

I have since asked Sarah for a complete refund , which she has refused and so I have escalated to the AirBnB reconciliation centre where a full refund has been supplied.

I have suggested to Sarah that with a small investment and some care and attention to the letting of this apartment on AirBnB that it could become an attractive let due to the location but looks like she has ignored my suggestion.

Regardless, my fault for booking a property without positive reviews and lesson learnt but hasn't put me off further booking through AirBnB.
