lovely smallish hotel
this is a small hotel (family run according to the front desk). the front desk staff were lovely the concierge always seemed to be on duty and was beyond friendly and helpful - really great guy.
the rooms are modern, lovely comfy beds. we stayed as a family of 4 with 2 small children (ages 5 and 6). if you were to stay here more than say 3 or 4 days with 4 people the rooms are pretty small. probably the smallest in our whole U.S stay. as a couple it would be fine. 
it is situated on bush street right on the corner of where china town starts. really convenient place to stay. walking distance to market street for shopping and transport and also china town and union square.
we also stayed at the Westin St Francis - i looooved this hotel. but you need to find a deal as otherwise it is quite expensive for you stay for a week - see my other review
