Good location for exploring SFO
Recently stayed with husband for 4 night break in SFO. Booked Omni based on other trip advisor reviews and we were not disapointed. Great customer service on check in. One of the first checks they made was if we wanted to visit Alcatraz, explaining that the trips are booked up heavily in advance and suggesting they made a booking immediately for us to ensure we didn't miss out.
We booked a signature room and found this to be a really good size with an extremely comfortable bed. The walls must be thick as for once we didn't hear any other guest noise which was impressive considering our room was immediately across from the lifts.
Only improvements I would suggest to Omni is better bathroom products, fluffier towels and complimentary water on arrival.
In terms of location, it's a short walk to the Ferry building (great spot for lunch) and its a 25 minute walk to Coit tower taking in China Town and Little Italy. The tram runs directly outside the Omni although it's only 15 min walk to Union Square.
Top tip: have good walking shoes as it's so easy to explore a lot of SFO on foot from the Omni.
