Greg's place, to me, exemplifies the original spirit of Airbnb. If you want to travel where you get to be a part of the community you're visiting rather than displacing it, this is your spot!!
If you are looking for a professionally-cleaned, sparkling, trendily-decorated generic Airbnb/hotel room, this is not it. You are sharing a real home with a longtime local SF resident, which does mean the house is lived-in. Greg went out of his way to make sure I had everything I needed when I stayed with him as a base of operations during a work conference. Sure, there may be some paint peeling and marks on the walls, but the linens were crisply fresh and check in was easy. In particular I liked this location because, unlike many spots in the city, it was quiet and peaceful at night, easy to sleep well and uninterrupted.
In short, if you're finicky about your Airbnb environs and you're using it to book upscale hotel alternatives this might not be the spot for you, but if you're looking for a good stay with friendly locals, jump right in!
