I travel 365 days a year and mostly live out of hotel rooms, but I try to stay away from Airbnb and this is why.
Airbnb is burglars paradise.
If you are a professional burglar, there is nothing better than being able to rent a room for one night, copy the key and then return a few days later when someone else is staying there. Doing this is a lot easier if the place has no receptionist. Nobody watching the door and no surveillance cameras. The vast majority of Airbnb’s do not have anyone guarding the place at night and keys are almost always old fashioned keys and not magnetic ones, where you can change the code after each use.
This is not a big deal if you rent out on a monthly basis, but on a daily basis, you just have too many people with that easy to copy key in their hand.
If a person rents out a room in an apartment on a nightly basis, the key will probably be held by somewhere between 50 and 100 people in a year. So you want to have a key that can not easily be copied. Or at least someone who keeps watch on a place to make sure that someone does not return to a place with a copied key, after they have checked out.
I worked many years as a hotel receptionist, back in the 1990’s. I worked in several countries, at different types of hotels. In all places we would sometimes have people trying to steal from our hotels guests. these people would almost always work as night, because there was only one person on duty. The night receptionist.
Running a hostel out of an unguarded apartment is asking for theft.
