I think there are several factors to consider in this area. Your reasons are valid By the Sea; if it's a large complex I see no harm in giving the address but not the unit until you arrive. If, on the other hand, it is a private home more precaution is required. This happened to me recently: he called and was on his way, so I told him the exit, the turn and a safe place to pull over and call me for the house number. When he called he said he would have to reschedule so I didn't give him the number and he didn't ask for it. When he did reschedule 2 days later I gave him the house number and he said he was on his way. He never showed up, nor did he call or email until the next day. His excuse was valid but that didn't make the prior 24 hours any less nerve-racking for me.

Intuition plays a huge role as well. If I am able to chat and get to know someone first I feel safer giving my address but as Alyssa said not until the appt is confirmed on that day. If someone insists on having the address days in advance that is a huge red flag. The 2 call system may be a little inconvenient or it may be a frustration depending on how its done. Most providers will/should give the area/cross streets for convenience, immho. The convenience and ease of parking when seeing a therapist is usually noted in reviews or should be.

I know of one provider who has solved this problem by giving new clients the address of a rather nondescript office building that's across the street from her real address.  Yes, I was slightly confused when I pulled up in front of ACME Dental Supply, but when I phoned her, she simply told me to go across the street to unit 123 in the pink apartment complex.  Seemed simple and effective.
