We were met on arrival by Gino, that very pleasant owner of the studio, who made things very simple for us during our stay, with a few pointers about the neighbourhood and the usual practices of the building (which doors to keep closed, trash collection, etc.).
The location of the studio is even better than we expected, with very easy access to transportation (cable car and Muni), and even restaurants located literally downstairs!
Advice for future visitors: our best decision was to buy the Muni pass from our first day, that includes all possible transportation in the city!
