My partner and I stayed at this Homewood Suites for a weekend because of a wedding in nearby Alameda, and I would say this is just a barebones Homewood Suites like any other.
First of all, the location of this hotel is kind of random. It's directly off the highway (so in that sense, it's convenient), but it's surrounded by somewhat of an industrial park and port. The one redeeming quality about its location is the waterfront views from the budding on the left (if you're looking at the water). You're right on the marina, and it's a *great* view to wake up to. However, if you're in the "city view" rooms, you look onto a highway and there's no real point of staying at an "oceanfront" hotel... That is a big distinction, because the view was by far the best aspect to this hotel, and so if you don't have that view, there really are not many positive points to speak of.
I also got the feeling that this hotel was old and had seen better days. The room, while big, was somewhat drab. It's just a typical Homewood Suites with regard to the layout and kitchenette amenities. Maid service was hit-and-miss: one day they didn't come until we called and said we hadn't had service all day, and the next day the were aggressively knocking at 830am. The breakfast in the main lobby was fine, and had a waffle station.
The front desk seemed kind of clueless. I think some were brand new, because we had to "ask" for an upgrade, even though it's normally automatic since we're Gold with Hilton. In that sense, it's not a typical Hilton property because there wasn't that extra customer service you would get at a full-fledged Hilton or at a Hampton Inn.
Overall, I can't say that I would recommend staying here over staying somewhere in downtown Oakland or else on Alameda Island. The nightly price was cheap ($99), which is what drew us here. For that price, I can't really complain. Make sure to get an "oceanfront" room, though!
