So this is a two-star motel, but it was perfect for my stay. The staff is very polite, friendly and accommodating. The location is on a main road, but quiet.
The location is just right:
Very close to the marina.
Right next to Chestnut st, with many places for food and refreshments.
Walking distance to the Presidio
Walking distance to many other scenic sights.
Close to public transit to take you downtown.
If you enjoy waking up and taking a stroll to the marina, getting coffee and sandwich on the way; and overlooking the Golden Gate Bridge as you're sipping your coffee - this is the spot for you.
My only real regret is that I couldn't stay longer.
