You have to understand what you are getting before moving in here. I do not know where some of the prices are coming from on here but my girlfriend and I signed a 6 month lease for a nice 2 bedroom for less than $1,000. Even after our 6 months was up, our month to month onyl increased $100. It is by far the closest place to all the nightlife and dining in Old Towm is thats what you are looking for.
Now that all the good things are said, the management and upkeep is not the greatest. It takes the management mulitple times to accomplish anything and it seems any upgrade or improvment is more of an inconvenience to the tenants that helpful. Our apartment started to fall apart within weeks but becuase the deposit was only $250, we didnt really care much to worry about keeping up with the place knowing full well how they treat those moving out! Be prepared NOT to get any of your deposit back and depending on poorly you maintained your residence, fines on top of that!
Know what you are looking for before moving into San Marin!
