Jack is a great host, genuine, friendly and always around to answer questions.
The room I stayed in had views over Twin Peaks, it was quiet, warm and had a comfortable bed.
The area is good for mixing with the locals and Jack had some top tips for good food nearby.
I used Uber pool to get around, it was around $5 to the Castro and around $9 to the Pier Area - you also get to meet others on your journey!
