The host gave me a detailed instruction on how to get to the place before I came. So, I didn't find any difficulty on finding the place and checking in. There was one minor confusion about the building's code, but it was solved immediately.

The place is really clean, but as describe, is quite small. I personally don't mind, but people with claustrophobic might want to inquire more details about the place.

As for the location, it is very close to Austion Metro Station (5 mins walk), as well to Jordan Station (10-15 mins walk).
The neighborhood has several restaurants (including one good dim-sum place called dimdimsum that was once visited by Anthony Bourdain). Convenience stores are easy to find too.

I only met the host briefly. He seems to be friendly and understanding.
