Yumi's place is in a great location on Nob Hill, walkable to many different parts of the city, keeping in mind some hilly terrain, and close to bus routes. Nearby Polk street has interesting local shops and restaurants. The room itself is small but comfortable, with a good-sized bed and closet and a window for fresh air. The bathroom is also small but modern and clean. There are a few other rooms on the same floor that are also rented to students and business travelers. I found Yumi and her assistant Catharine to be friendly and easy to reach by phone or in person. I stayed here for one month and would definitely stay with Yumi again, especially for the location.
