Moved in here at the beginning of the pandemic and got a sweet deal with stunning views of the bay (pro tip: try to secure a room that faces the Salesforce tower and has balconies, it's worth it). The building itself was built in the 60s but got a pretty modern update so everything inside feels very new.
Staff is very nice and accomodating. Maintenance team also responds pretty fast and the whole premise is usually kept very clean. There's a laundry room on each floor so that's very convenient. The gym is compact but should fulfill all the workout needs one can have.
The location is really great too. If you are looking for food or nightlife you can easily walk to Polk street or Northbeach/Chinatown. Union Square is just down the hill but be aware of the walk uphill if you decide to go there. There's also many nice bars one block down the street on Bush.
In overall this is the best place I have stayed at and I feel sad that I had to move out. Anyone who's interested in renting here should definitely give it a shot and tour the place.
