Don't do it!
People trying to go outside the system
(1) are trying to not pay the airbnb fees
(2) are looking for special treatment and will bother you till the end
(3) will negotiate, discuss, harangue about everything in your contract
(4) you will need to run after them for payment.
I just had a person who wanted to book my whole highest season the entire month thru HomeAway.
He found my number on the web. I told him he could visit the property but since I'm not there he would have to pay my property manager 30 euros, like a meet and greet, for someone to come and open the door.
He didn't agree, "it's not the money its the principal", started negotiating and didn't want to pay to be able to see the apartment so I apologized politely wished him a good vacation and blocked him on Whatsapp.
After searching all around the area several weeks later he decided that my property was best.
The nightmare started. His wife (!!) contacted me with her phone number since he was blocked.
She didn't identify herself as his wife. She pretended to just have heard that i had a rental in the neighborhood.
This started 2 weeks of haggling, discussing the price, asking for extra services, telling me my policies were not normal, asking for extra linens, not wanting to pay the electricity fee, ...
I kept trying to blow them off they kept coming back.
I've lost sleep over this not knowing how to turn them down firmly and politely without angering them so that they leave a bad review on my website.
It's not worth it that's the last time I'm contacting someone who wants to visit the property;
In general they are taking their rental way too seriously and importantly and will annoy the heck out of you till the end.
