So here's the sitch:

We own a flat (apartment) with a shared garden where Evelyn plays and we hang out our washing. We share this garden with 16 other flats, although not everyone uses the garden.

One of the flats has recently been sold and the new owner is changing a window into a door that would directly access the garden, which isn't really an issue for us, apart from the fact that building works will likely be dangerous for a very curious toddler.

The issue is that she is also advertising the flat as a holiday let, meaning that strangers will have access to the garden and potentially my daughter. Strangers who do not have to provide any kind of references, unlike long-term renters, and who won't care about the mess they leave since they'll just be there for a couple of days.

We're not happy about this, and will get in touch with the owner to let her know this.

But what would you do?

How far would you take it if you didn't get a good response from the owner?
