They gave me the wrong location for me to pick up keys from a lockbox. I spoke with a representative of the rentals company before arriving & they ALSO gave me the wrong address for lockbox. Be sure that you're given the proper address for pickup.
Next, they ask you to use a fake name and lie to building personnel that you're a guest of a tenant. I didn't feel comfortable doing this, so I just avoided conversation with anyone. They also make you enter through a garage parking lot upon arrival so as to not arouse suspicions that you're an AirBNB customer. I didn't feel safe going down into the unstaffed garage lot with my luggage late at night just to avoid the main entrance.
Third, they asked me to download an app to unlock all buildings/amenities. While I didn't mind the app download itself, I hated that the app is a huge invasion of privacy and takes photos of all of your scanned entrances. I was uncomfortable knowing guests and the host could see photos of me on the app.
