I stayed in Room #6 for ten weeks. Overall, I had a good experience! General vibe is like living in a boarding house. Here's the info I wanted when I was looking into staying here:
The neighborhood is very safe. I wondered if it was more "TenderNob" than Nob Hill, but it's pretty firmly Nob Hill. I never felt uncomfortable as an easily-startled small female.
The location is awesome. I was within walking commute to my Financial District summer job. Having a Trader Joe's two blocks away is absolutely priceless. Tons of great restaurants, coffee shops, etc all along Polk St.
This room has its own private attached bathroom. Guests are expected to clean rooms and private bathrooms themselves; any cleaning supplies beyond the community vacuum you must purchase yourself.
The kitchen isn't totally fully outfitted. On my floor (first floor), there was a microwave, a stove/oven, and an electric kettle. There were a couple old pots and some dishes and utensils that prior guests had left behind. Some spices and leftover dry goods available for grabs too. I ended up buying my own dishes/utensils since I was there for a while and wanted to know that stuff was clean.
The furnishings in the room were a bit worn and mismatched, but completely functional.
Overall, a good experience, and MUCH cheaper than trying to rent a studio or one-bedroom AirBNB. Lack of frills was made up for and more with the great location, clean/quiet building, and quick communication by Yumi and assistant.
