In the lead up to our trip, I sent emails and texts to our host but never
heard back. Finally, I called their listed phone number and got through. My
advice to other guests who are having trouble connecting is to call...and
call again...until you get through. Irina manages the Airbnb page but isn't
always available. Gregory handles the day-to-day management and is present
on site. Eventually, you should get through to one of them. My impression
is that once Airbnb confirms it, it's confirmed on their end--even though
they aren't the best about answering follow-up questions.

The room itself is comfortable and clean. The bathroom, which was also
clean, is shared by a maximum of 6 people (Gregory, Irina, and guests in
another rented bedroom). This wasn't a problem during our stay but it's
something to keep in mind. Most importantly, the location is
unbeatable--it's a great base for exploring the city. Down the street from
great cafes and food spots. Walking distance to key attractions. And
well-connected by MUNI to anywhere else you might want to go. Gregory is
super nice and helpful-he had great tips for us. Despite our initial
difficulty connecting, this was excellent value for money and a great place
to stay. Would stay there again!
