Karina always replied very quickly to all my questions. The apartment is in a very good location, a short easy walk to Union square, there is a Whole Foods supermarket at the end of the street and it is easy to access the freeways. The apartment is spacious and very light due to the large loft style windows. Note it is very light even at night time if you are used to sleeping in a very dark environment! We visited Napa for a day and it was very easy to drive there from this location. Overall a good place for a couple to explore San Francisco and surrounds from.
