Thank you all for the wonderful responses so far!
Me and my friend might be going in a different direction now since we've figured the AirBnB's are way too expensive, especially the one in SOMA.
We found room rates at The Kabuki hotel in Japantown for a lot cheaper - would be saving us $700-800 overall. How is the area? I'm assuming the area is good and there is a lot nearby, especially with Izakaya bars etc. Plus, like most people said, its easy to Uber anywhere.
Thanks again for the responses.
