It was my first stay with airbnb and it couldn't have been a better choice. The room is spacious and cosy and the views not only from the living room but from Protrero Hill in general are stunning. To watch the firework at New Years Eve I just walked a few yards round the corner and had a fantastic outlook at the city.
Cathryn is a charming and very easy going host, ready to give you any advice you need to explore the city. She even took me along to show me some sites I'd never seen as a normal tourist which was extra fun.
Going downtown is simpel since there are two bus lines running very close to her place. I sometimes found it a little difficult to find my way back, since I never knew where I would be at the end of the day. But everybody with a less oldfashioned mobile can load apps for public transport and the problem disappears.
