Treehouse Hotel Silicon Valley can take a conference of up to 510 people theatre style, a seated dinner for 320 or a board meeting for 20, all on one site with guest rooms upstairs. The hotel stands at 1100 North Mathilda Avenue in Sunnyvale, California, and belongs to the Treehouse brand. Seven event spaces are listed, from a 4,600 sq ft barn to a 444 sq ft private dining room, with an outdoor lawn and a café that can also be booked.

Marigold and Poppy are twin 675 sq ft rooms for groups of 20 to 30, set as a boardroom, a U-shape or a classroom. The events team offers planning support and in-room technology, and a group can combine its event with a block of guest rooms at negotiated rates.
Weddings and receptions
Ceremonies, receptions and full wedding weekends are on offer. The Event Barn and the Event Lawn host receptions, the Playground Patio is used for first looks, and getting-ready suites can be set up in an event space or a guest room. Rehearsal dinners take place in an event room or at Valley Goat, the hotel restaurant. Three wedding packages are published, each with a private menu tasting, and couples may bring their own suppliers or choose from a preferred list of planners, florists and photographers.

Accommodation
Guest rooms range from king and two-queen rooms to patio rooms, a Perch King, junior suites, a cabin suite with a soaking tub and two-bedroom suites. The hotel does not publish a total room count, so ask how large a block is available on your dates. The hotel has a pool and accepts pets.
Catering
An in-house culinary team writes seasonal menus built on local produce for every event, from a working lunch to a late-night snack after a wedding. Valley Goat, led by chef Stephanie Izard, serves globally inspired dishes, the Backyard Café covers coffee, juices and lighter food, and the Beer Garden pours more than 30 beers on tap. The hotel donates surplus food and serves with stainless steel instead of single-use plastics.
History and setting
The hotel presents itself as a retreat for ideas in a business district better known for tech campuses than for event venues. Alongside the Event Barn it has a recreation center and a beer garden, which gives a team somewhere to meet informally after sessions. Esquire included it among its best new hotels in the world for 2026.
Getting there
The hotel sits in north Sunnyvale, close to US 101 and State Route 237. San José Mineta International Airport is the closest airport, and San Francisco International lies further north on the Peninsula.
