Fing! An app, as suggested on Michael Bazell's podcast. Basic version is free and will tell you what's connected to your network. Haven't been in a rental property in years but I constantly use it just out of curiosity, in bars, coworking spaces etc. The app will tell you the IPs of all connected devices and you can do port scans as well (nmap is better but less convenient). One time I managed to access the router of a coffee shop while waiting for my drink using default credentials, and from there got the video feeds of their security cameras.
