We had a lovely time at Massimo's studio flat/apartment. It was very clean and tidy and well located for public transport. It is also within walking distance from Presidio park and Golden Gate park both of which were beautiful. Massimo left very clear instructions and some tips on where to go in the local area as he was out of town for the week, but we did manage to meet him on our last day, where he kindly agreed to look after our luggage before we went to the airport. He was a very warm and friendly host and I would strongly recommend staying here if you are visiting SF.
