It has been one of the best airbnb experiences I ever had.
I rented a room in Maryam's and her husband's house for 3 nights.
Since Maryam was travelling, I did not meet her, her husband has been the host. He took me out for dinner & drinks in the nearby Mission Street / Valencia Street neighborhood and provided me the typical SF experience. ;-)
He is very open-minded, likeable and friendly. he was very patient to explain everything about the house, the City, the neighborhood etc.
The place has been perfectly clean. The living, kitchen and dining areas are well equipped, all is new and tastefully designed. The room itself is on the upper floor, across their bedroom and very spacious. The bath room is being shared with the hosts, it provides a nice view in the morning over the SF skyline while showering.
Since I had a rental car, I cannot say anything about public transportation, finding parking in front of the house was pretty easy. The neighborhood (upper market street / Noe Valley) is residential, quite, safe with a lot nice victorian houses.
I would definitely stay again there!
