What is not to like about a masterpiece of Steamboat Deco architecture that is:
-2 blocks from the ocean
-On the Muni (L)-Taraval streetcar line
-On the #18-Forty-Sixth Ave & and 23-Sloat bus lines
-2 blocks from the Zoo
-Nestled amongst the quiet Parkside District
I included references to public transit because San Francisco has one of the absolute best systems in the country. Parking in the City By The Bay is difficult and expensive, so unless you HAVE to bring a car, you're better off taking the bus and trains.
The Ocean Park Motel is far enough from the frenzy of downtown and the bustling neighborhoods to be quiet, but close enough so that you can get there quickly. Your room will be comfortable, clean, and quiet, whether it has one or two beds. Kitchenettes are available for a slightly higher rate. This will be quickly offset by pruident travelers who don't want to pay for restaurant meals. Furthermore, seafood lovers will save a ton of money by going a few short blocks to Sunset Super grocery at 40th Ave & Vicente Street, where fresh Dungeness crab sells for less that $5 per pound (compared to $18 per pound at the Fisherman's Wharf).
At the end of your day, you will enjoy lounging in the motel's hot tub, then settle in for a restful night in your cozy room.
Getting to SFO airport is simple, but allow yourself about 40 minutes to get there, to account for traffic and allow a bit of breathing space. Depending on which route you take, downtown is between 20-30 minutes. The Golden Gate Bridge is a short drive up 19th Ave (15-20 minutes). Off-street parking at the Ocean Park Motel is free.
In summary, you will not be disappointed here; a perfect complement to one of the world's most beautiful cities.
