1. A lockbox with a combination. On the street near the apartment. Enter the code, get the keys. Put them back in after checkout.
2. 24 hour convenience store across the street. Give my name/number, get the keys.

There is also a company called Key Cafe with hundreds of locations that some people use. Similar to the lockbox solution but at a cafe or store, not on the street. There is a monthly fee for that service.
