The location itself perfect but the place was so clean and nicely equipped, my one week of work trip felt like I was almost back at home.
It was spacious and clean.
The China town was just a couple of blocks away and less than 10 min walk to the Union Square.

There where plenty of places to grab food from and go for a quick shopping even after work because everything was so nice and close.

I didn't get to meet Greg in person (the place has keyless access code which was quite convenient) but he replied to any questions promptly.
With the access code though, I've received the code a couple of hours before the check in and because I was travelling internationally, I didn't really have the access to Airbnb app/site to grab the access off line. But SFO has free wifi so I had no problem getting them before I took off to the place. So I'd been anxious for new reason. Everything worked out perfect at the end.
