Comfy, boutique hotel
We stayed a weekend in October at the Tuscan and really enjoyed it!
Pros
1. Location! Less than 2 blocks walk to Fisherman's Wharf. Close to the F line and 8x MUNI line that takes you into Union Square. Trader Joes is nearby for your grocery needs
2. Service - valet was very helpful in flagging down a cab for us during a busy weekend. The front desk was extremely friendly for all of our needs
3. Room - small but very comfy. We knocked right out in the comfy bed. We were lucky to get a corner room away from the street which really added to the quaint, relaxed environment. The room is nicely furnished and decorated with up-to-date fixings. Shower was a little on the older side but that is purely aesthetics, functionality is fine. 
4. Mini-fridge - it is not a sensor operated fridge, so you can store things you buy at the local grocer while moving things around
5. General area/fireplace - if you are waiting around for your ride, enjoy their lounge, which is equipped with a fireplace and books. Nice touch to a boutique-like atmosphere. 
Could Improve
1. Only slight downside I could think of is the first whiff of the room when we entered. It has some residual of the old days when rooms were smoking. It didn't bother us except for when we first entered, but turning on the AC took care of that. 
Overall, we thoroughly enjoyed our stay at the Tuscan Inn and will gladly stay again.
