Traveller reviews
Romana “Great hotel for solo travelers and business people”
22 Apr 2026
The hotel is located in an area that allows easy commute to all major attractions and conference venues as well as simple public transit commute from and to SFO Airport. It has small but well designed rooms great for one person or a couple and a nice communal area with a kitchen, lounge, and laundry on the second floor. Also there are a couple of great restaurants next door you can go to for lunch or dinner.
