Our host emailed me prior to our arrival to ensure we were connected through WhatsApp and that I had contact information of the woman who would actually be meeting us at the apartment (who also reached out to add her welcome).

Upon arrival, we received a thorough explanation of where everything was and how it all worked, including the security in the building, locks, etc.

After we'd been there a day or so, both checked in to make sure we had everything we needed. They both gave us local recommendations and tips on dealing with cabs, etc.
