Just finished my stay and wanted to share a few thoughts. FYI - I have some built in biases having formerly been in mgmt at a 5 star resort. Also, I have been out of the biz for awhile so I am not all the way up to speed on the latest hotel stuff but know enough to be dangerous. Here are my thoughts on the Westin St. Francis - The Union Square Area is very energetic and vibrant and no hotel is better located at Union Square than the Westin. It is an old property but has had plenty of life breated into it. I had a tower room (an upgrade, more on that below). Fabulous view. As for the room, you can tell this was an old room they have attempted to inject some modern feel too. Room size is great. Water pressure in the shower was great. The Heavenly bed thing is for real, really good. But, the bathroom was not really what you would expect at a property of this caliber. Small tub, no fan, that sort of thing. Overall a very good room but not of the 4 star quality you might see in a "younger" hotel. At check in the desk agent noted that my gal and I were quite tall (6' and 6'5") and that my hotwire reservation got us a double bed in a small room that is not in the tower. For $30 more per night they could upgrade us to a bigger bed. I agreed so long as they agreed to put us in the tower, which they did. This is not an unreasonable thing to do in the hotel business and the staff handles it well. But, it is something hotwire users need to be aware of. FYI - For a vacation with my gal it was worth it. If I was traveling alone on business I would have seen no need. This hotel is clearly aggressive about filling rooms. The day before my stay I checked it out on Expedia for the same dates. $100/night, $16 less than what I paid through Hotwire. Expedia was clear it was a small room with one double bed. Add the $30 and it is a heck of a deal. Really a great staff at this hotel. Top to bottom. Be prepared to pay for EVERYTHING here. There are no freebies. They will put a couple of small bottles of water in your room at the rate of $4.50 each. I understand the economics of this but it really feels wrong. Also, ice machines are on each floor but if you ask for it from room service you are charged for the ice. What happened to the days when you could give the delivery person a few bucks for the effort? We did not have a car. I think it is something like $40/day at the Westin. I would avoid this as driving the Union Square area is no fun at all. A few recommendations for the area. The top floor bar at the Grand Hyatt on the other side of Union Square is GREAT. GREAT views. Get there early for a window view of the bay at Sunset. Lefty O'Douls across the street was good for breakfast. Great bloody's at Jack Foley's. The Top of the Mark (at the Mark Hopkins) also has great views. Just around the corner from the Mark Hopkins is a neighborhood restaurant named the Nob Hill Cafe. Excellent food and a very affordable wine list. Great Italian Food in North Beach. Jack's by the wharf sucks. Expensive, no good and surly management. Yes, we pretty much ate and drank our way through the city................. Cable cars were too crowded and the wait was too long to get on. It runs in front of the Westin but other than maybe to go to the Wharf I would take taxis or walk.
