Spirit House is not a company. It is a private hilltop retreat home and groups up to 20 or so rent it over night for 2 or more nights. Spirit House is perfect for small group retreats of all kinds, from meditation to yoga to company staff retreats to family and friends reunions and celebrations. It is close to San Francisco but a world apart, located in a beautiful country valley and surrounded by the natural world. In addition to their overnight guests, renters can also hold events for up to 80 for an additional fee.
