@John0 @Peter0 - one of the most common themes about issues arising with guests is the fact that they simply do not take the time to read the detail - whether the descriptive and miss vital things such as it's a room in a private home, or an apartment where the host lives above (as in my case) etc etc and therefore most times disappointment guests feel is their own vision of what they thought they were paying for and the reality of what they get -
Most often it is the airbnb 'first-timers' who take the least time to read details. I lose count of the amount of guests who say can I park outside - when the opening line of my listing includes 'traffic-free' street. Guests even contact me when enroute and ask me for the address - so they haven't even bothered to read the itiniary and have set off without even looking up the address or how to get here. Daft or what?
Guests rarely say anything to your face - but instead might make a comment in a review or give you poor star rating much of it based on their own lack of attention to detail. I am lucky to live in a superb location and tend to get 5 stars across the board - location, communication, cleanliness, accuracy and then a 4 star for value (despite parking vouchers, free wifi, free breakfast provisions, own come and go as you please entrance/exit, free use of own kitchen, high quality everything) which simply means, we loved everything but we'd like to have it even cheaper despite it already being 50% cheaper than a hotel in the same area without all the extras. go figure!
But if the stats are est 1% unpleasant guests, 4 to 5% we wouldn't welcome back for a variety of reasons - then it's not at all a bad average.
Addressing your original question John - if a guest is behaving badly in situ, you just need to have a quiet word and ask them not to do whatever it is that's irking you. Reviews work both ways - and as others have said, hosts can read between the lines. In a similar conversation a host suggested a host code such as simply stating XYZ stayed at my property for X days in X month, X year - simply as a warning to other hosts that you are not recommending the guest, there were issues but not ones of significant damage etc to warrant saying anything else.
I have used that once but it was a guest that never left a review anyway (I knew they wouldn't anyway as the reason for use of stating the dates only was due to their very selfish nature, lack of consideration like going out every night and leaving every single light on and leaving my place dirty beyond reason)
So perhaps we need to spread the word amongst hosts to just state the dates they stayed as a signal that the guests were not very considerate or respectful. What do you think?
