Great Apartment, fantastic location! Tomasz was very helpful and had everything in order for us. He even found us free parking behind the apartment building for the duration of our stay. This is definitely a non-issue but I wanted to mention here that the apartment does not have air conditioning ( not that it is required in SF!) and even in September, we did not miss it at all!
Even though four of us stayed comfortably at this apartment for four days, I think it would ideally be perfect for two to three guests.
I would totally recommend staying here :)
