This boutique hotel in San Francisco is between the convention center and Union Square. The historic building first opened as the Keystone Hotel in 1913 and received a multi-million-dollar renovation in 2003, along with a new name. The hotel rooms are intimate, with the smallest rooms just providing a twin bedroom, and a queen bedroom sharing a bathroom. The largest rooms are queens; a family may need multiple rooms to be accommodated here. Cribs are available for free, and complimentary coffee, tea and muffins are served in the morning. Rooms feature flat-screen TVs, iPod docking stations and free Wi-Fi. Parking is only available via valet, for a fee. Coin-operated laundry facilities are on site. For gym access, guests must use the fitness center at the hotel across the street for a daily fee. Onsite dining is available at The Keystone, which is open from lunch through late night and serves brunch on weekends.
