I came here looking for some ideas after a google search and I know the thread is old but I'll add my two cents 🙂
We started our Airbnb in Feb 2020 and have learnt a lot over the last year! We rent out all of our home and move all our own personal belongings before hand.
Things we include in our listing is our own in house entertainment system with over 2000 films and 800 box sets, all availible via the Roku connected to the TV in the lounge. We have colourful bedding to match each room, different coloured towels for each guest that compliement the room and provide an extra set of bediing for people, just in case they need them, we don't charge extra.
We provide Tea/Coffee/Hot chocolate, Milk, biscuits and/or chocolates and a bottle of wine for people staying for 7 nights or more. I fail to see the point of flowers as they just die in a few days, but they do look nice so include them now (although one guest left us some Lillies and stained our table cloth, but it was a nice thought!). All cleaning supplies including anti bac washing up liquid (used an Airbnb once and they left no washing up liquid!) We leave bin liners for the bins (again stayed in one without them!). Washing power/pods, softner and delicates liquid and of course use of the washing machine. We have a hair dryer and we have enough decent antislip hangers in each wardrobe that match, we hate cheap plastic hangers!
These were the things we started off by doing, we have now since added a Google Smart Speaker to each bedroom and kitchen (cost £15 each! Bargain!), already had one in the Lounge and Master bedroom. A fully stocked spice rack (use by dates of each spice are in the house guide). I added a Retro Gaming system to the TV (I had a Raspberry Pi sat doing nothing so why not!). Also charging cables for each guest with Lighthing, Micro and C adapters (so far none have gone missing). We also printed off a 2D barcode for people to scan for the WiFi code, which is sometimes easier when it comes to kids connecting to the WiFi.
My crowning acheivement (if I do say so myself) is a 'House Handheld', my old Mobile phone (a Pixel 2) which works only on WiFi, with Spotify (to stream to the Speakers), access to the aformentioned entertianment system, a Web Browser, JustEat (with the post code programmed), calculator, Maps, a Taxi app (there is no Uber where we live), a WiFi remote app for the TV, the Roku App, access to Hive (the heating system), Tuya Smart to turn on and off the Smart lights in the bedrooms and outside lights, a copy of the house manual as a webpage, the wifi login detials and a link to the Airbnb Guide Book we have created. It's a fully lockdown system (ie people can't mess with the settings) and if it gets pinched is tracable via the 'Prey' app. I have a little charging dock and magnetic charger clip in the bottom for it to charge. We have yet to have a guest use it as I've spent months testing each feature to ensure it works. I've personalised it all with our house name and custom icons for the apps so people know it's unique to us!
Once thing that our friends who host did were to get some Maps of the local area printed, they live in a rural area with great walks and they got there names printed on them, I thought this was genius!
We are hosting a local family next month that are moving out of thier house while they have some work done, so we will put there initials on some small/pocket sized hand sanitiser for them (one of our businesses is personalised products!)
Anyway thats my 2 cents 🙂
