UNDER NO CIRCUMSTANCES STAY HERE!
He ignored all our messages and we were left stranded in Florence with all our luggage and nowhere to stay. Air BNB dealt with the situation admirably as a company and offered full compensation without any prompting. But this host is not at all to be trusted - I have subsequently seen from other reviews that he is a repeat offender in terms of not responding to people and leaving them in the lurch. He should be banned from Air BNB.
I repeat - do not stay here.
