Hello @Paul1723
Have you had a look at Airbnb Help Centre and the useful tutorials on these forums. If not please take the time to read them as along with the extensive content on Airbnb's website - they will help you become familiar with the basics and will answer the majority of your questions
1) I have accepted the Booking - When do I receive the Guests details? ie name, address, email, phone?
You will see their details on your booking confirmation. You don't receive their address.
2) Is it correct that AirBnB send me the payment the day after the guest checks in? Is that correct for a 6 week stay?
I think you get the first month paid out for the long term stay initially, but don have a look at Airbnb's long term stay policy on Airbnb Help centre
3) I set a £100 Damage Deposit - is that just something AirBnB handle in the background ie I dont have to collect/refund that money?
Details of how Airbnb deposit works is outlined in Airbnb Help Centre. They handle it. No money is collected - a charge is held against the visitors payment mechanism.
4) What info am I allowed to ask from the Guest? (I dont know what info I might need but don't want o break any rules)
If you want to ask specific information from a guest you need to put it in your house rules. There is no set list of what you are allowed to ask - obviously nothing discriminatrory.
For example you can't add a minimum age of 21 unless your apartment block imposes this restriction on you. Airbnb accepts anyone over 18.
My top tips for you ;-
a) make sure you have your own home insurance for STRs in place
b) turn off IB until you become familiar with how Airbnb works to avoid costly mistakes
c) if you host remotely have CCTV at your properties
d) don't take long term bookings when you first start, I would suggest you limit stays to a few weeks.
Finally Airbnb asks you to install a photo of yourself on your profile not your company logo as it installs trust - would suggest you do this along with completing a description.
