Greg's apartment is great! It is in the perfect neighborhood to discover San Francisco. You can easily get to Pier 39 and the restaurants in the neighborhood are great. It's also a safe district.
The room itself is like in the pictures and Greg is a great host. He recommended many places and we enjoyed our stay in SF. We were even allowed to leave our luggage after check-out time in the apartment so that we could enjoy our last day in the city.
