I know many reviews boast about the parking which is great. However we used public transit for our entire visit, as we were so close to the BART station. Jen is a very responsive host and the place is incredibly clean! We felt extremely safe staying here and the building was incredibly secure!
I will say if you are not used to urban environments or seeing a homeless population consider staying in a suburb. Oakland like much of the rest of the country is continuing the battle for affordable housing. We knew this going into our stay being in Oakland many times in the past.
