There are three flats, each with its own front door opening onto a shared stairwell; and a common front door that opens onto the street. The main front door has a mail slot. There's no 'mailbox' - mail deliveries land on the doormat. Someone picks it up and puts it on the first three steps when they come in or go out.
This works fine as long as my neighbours are actually neighbours. If they're some random tourist from anywhere in the world, not so much.
This is not a "house" - if it were a house, it would be a six-bedroom mini-mansion. There are separate houses on this estate, and two larger blocks of flats. The larger blocks have entry-phones and so on. This is the only block with as few as three flats.
They are nice flats, luxury even, in an amazing location. Unfortunately the developer (early 80s) went broke, and so there are some loose ends that were never properly dealt with, especially the handling of rubbish, and the whole matter of investment properties, empty properties, and ultra-short lets. There are no children.
As I say, it would all be fine if my neighbours were neighbours. Even if I didn't like them, we'd have a shared interest in making things work. I don't have to like my neighbours; I just need to be able to find them, so I can talk to them about issues. The landlord of this AirBnB property lives 600 miles away, in a foreign country, and has never lived here.
