@VisitSanMiguel0....Now there is a name it is hard to respond to, so I will just call you V.....ok!
V, you are accepting the wrong guests! If someone comes to me with a statement like..."We have seen your lovely listing and my husband and I would love a few days away from the kids" ....bingo, I can't hit that accept tab fast enough! They have come to me in a passive complimentary way and I know they will be good guests.
When they come to me and say "I am on a busines trip to your town, do you have, this or that, free Wifi, offstreet parking, what sort of bed is it!".....they will not be the guest for me! They have come to me in an aggressive manner with a mountain of requests......and V, hagglers do not make good guests!
You must analyse every word in a guests approach to you and I can tell you now, your sense of good judgement is no different to mine, you just have to exercise it! It doesn't hurt you to decline the odd request....as long as you don't do it too often.
I have had 120 + great guests through this property! There would not be more than 3 that I would not gladly want to see walk up my driveway and into my life again...hosting has been wonderful to me!
But I do think that I have had a fair bit to do with that....I won't accept just any Tom, **bleep**, or Harry!
V, it's your property, don't let the tail wag the dog, take control over who you allow to stay, don't just chase a booking, don't be afraid to say 'Sorry, on this occasion, no'!
Cheers......Rob
