This was our very first experience with airbnb and we are very satisfied with our choice. Greg is the owner of the house who is and excellent host. He was very accommodating with our needs including check in times.
We stayed for three nights. On our last day we didn't have the energy to go out so we stayed in except to go out to eat and we just felt really comfortable in our room.
I want to mention that the rooms are very clean and although then bathrooms are shared, it is very clean. Probably cleaner than most hotels.
In terms of location, I don't think you can find a better place if you are on tour. We were able to walk to fisherman's wharf and the Coit tower as well as the crooked Lombard St.
There are great places to eat nearby in short walking distances as well. We had pizza, Thai food, Chinese food and wonderful breakfast and a reasonable price all within a couple of blocks. Just search using the Yelp app and you will find lots of great inexpensive eateries.
If we visit SF again we are sure to consider coming again to Gregs place!
