San Francisco - Downtown

Why We Like It

  • Rooms are cozy and compact, but modern decor adds a fun, quirky ambiance.
  • Smack in the middle of downtown, within a block of every possible mode of transportation and an easy stroll to Union Square.
  • Proximity to the Moscone Center draws the biz crowd, but everyone will feel welcome.

The ceiling fan was quiet, and the person attending the door -in addition to the other staff members- was very friendly.

Rooms are SMALL but very clean and the bed was very comfortable. To be honest you spend more time out in the city and it’s located by all the best museums and shopping destinations. Easy to get to any bus or train from the hotel’s location.

Small, service was not the best but it worked for the night.
