A nice, but expensive, modern hotel on Geary Street in San Francisco, with good amenities, up-to-date decor, high-speed internet, and a good location.
I have spent just about a week at the Clift during MacWorld. The stay was comfortable, the people prompt and accomodating, and the facility clean and comfortable.
I stayed as part of American Express' Fine Hotels and Resorts program and that allowed me to get late checkout, a room upgrade, continental breakfast, and some special additions at this hotel.
The Internet access was a bit of a chore, since they had an unintentional block on all 192.x.x.x IP addresses at their router. This was resolved by their IS department on the second day, which was too long, but they were nice about it, and allowed me to use the systems in their business center if I wanted to (connected to a different set of routers, apparently).
Location is about two blocks further down Geary than the Westin St. Francis (where I stayed in October). Nearest Starbuck's is right across the street, and it's about 6-8 blocks to walk to the Moscone center, which isn't bad at all.
My "Studio Suite" is just about the smallest suite I've been in, with a curtain separating the sitting room from the bedroom (queen sized bed). To be honest, I'm not sure it is any larger than the 280sq ft room I was supposed to have before the upgrade.
Price is basically comparable to the St. Francis and other similar hotels, although there is no garage available here at the Clift.
I don't know that I'll stay here again, but mainly because it isn't that remarkable.
