The coziest co-working space in SF. Great people, snacks, home away from home to work, play, and hang. Love it here

So happy that this exists in the Sunset! It’s really nice having a third space that’s not quite home, but also not as stuffy as a corporate office. The team does a great job of creating an environment for working and fostering a sense of community - they often have local events like craft night and open mic night. First Fridays of the month are also free! Highly recommend folks to stop by and check it out 🙌

Wonderful coworking space! Homey vibe with snacks and drinks. The owner Serena is super caring trying to create a sense of community while also letting folks do their own thing. Great location.

Love this coworking space, it's a fantastic find. Super homey and tasteful, and a great spot to be creative and productive. The space itself is great - plenty of tables for work, comfy couches, and meeting rooms you can book. I love all the local art on the walls, it gives the place a real community feel. Serena (the owner) is awesome and so welcoming. Plus, the kitchen is stocked with snacks! Glad this randomly popped up in my neighborhood. Will be working here regularly!
