Roberto's place was as described. The bed was comfortable, the bedroom and living room are well equipped with heaters to stay warm in the cool season, convenient use of kitchen and fridge, overall clean. It's spacious enough for two people.
It is located close to a park, bakeries and cool restaurants to try out, all at walking distance. It is a bit further to go to the Pier but nothing crazy. Good spot to (re) discover San Francisco.
We rented a car as we had plans to visit the outskirts of the city. Unfortunately, may we mention that the car has been broken in overnight, while parked accross the street from the apartment. Not sure whether the holidays were a factor?
Overall, it's a good place to stay. I'd recommend it (without a car).
