We had a great stay in Arthur's apartment. It was extremely comfortable and very well appointed, with a huge amount of space. The kitchen was so well stocked with appliances and utensils, that it was almost better equipped than ours at home! We slept really well in the beds, and the bathrooms had ample high quality towels and toiletries.
Arthur has gone out of his way to provide useful information for his guests with a file containing shopping and restaurant recommendations, plus an iPad loaded with comprehensive information about San Francisco. There is also a desktop computer available for those that need it.
When we arrived we were a little concerned that the apartment might be rather noisy as it is located on the corner of a busy junction. However, at night it was extremely quiet and our sleep was never disturbed.
Before we arrived in San Francisco a friend recommended that we use Lyft for getting around. We downloaded the app on our phone, and used them several times each day. We never had to wait more than 3 or 4 minutes for a car, and all the drivers were friendly and helpful. The charges seemed very reasonable compared to usual taxi fares. To be recommended over public transport.
