Large flat with great views from all rooms, great facilities in the building, amazing gym, communal sitting areas etc. Clear and simple instructions on how to do things in the flat. V good wifi and TVs both in living room and the bedroom. Private bathroom also v clean and large. A "Whole foods"-type place to get food from just 5 mins walk. The underground stations also 5 mins walk.
The only thing to note is that SF generally has an immense homelessness issue which to foreign visitors will be acutely obvious.
