We had just come off a stay several weeks prior at the nearby Cypress Hotel, so unfortunately, my observations are inadvertently in comparison to our experience there.
To begin with, we flew into San Jose and when I called the hotel to request that we be picked up (what I was told to do when I called several days prior to our arrival), I was told that the limo was unavailable and we should simply grab a cab and the driver should come to the front desk for payment from the hotel. This system indeed worked fine, but please note that the hotel's payment does not include a tip for the cab driver, so be prepared to do that on your own. However, we noticed that during our 3-night stay, the limo never left its parking spot under the entry canopy of the hotel and we humorously believed that it was simply placed there to give the impression of opulence - it never actually went anywhere.
The front desk staff was aloof, but friendly. Any extraneous information about the hotel to make our visit more comfortable was received only because we asked the right questions, such as hours of breakfast service, pool hours, nearby restaurants, etc. The breakfast that was served each morning was plentiful, although the quality was no better than what one would receive at a chain hotel, however, the evening cocktail hour was much more than a glass of wine and some cheese and crackers. The selection of both beverages and hors d'oeuvres was tremendous, the staff were friendly, and there was enough variety available to make us regret having committed to dinner reservations following that each night. Included in our room rate, that in itself was a great value.
Our room was very clean and comfortable, however, the balance of the property was dingy and very much in need of a good upgrade. Also, the pool area seemed nice, but was unfortunately often surrounded by smokers (especially during cocktail hour), making it of no interest to us.
Overall, the location was good for business travelers to Cupertino, however, with the exception of the value of having breakfast and an evening cocktail hour included in one's room rate, I would choose not to return until the rest of the hotel is upgraded to match the cleanliness and quality of the rooms.

good sized rooms. good sized bed.
small showers.
try not to get a room that faces over the freeway though as the noise is quite loud overnight.

The overall experience with this hotel was very good. The room was very big with a huge and comfortable bed and big TV.
The breakfast choices were diverse enough and WiFi was also complimentary.
What I liked the most was the heated swimming pool and spa, open 24h.
Even though I haven't used it, they have a limousine service from and to San Jose airport.

The Cupertino Inn can have an unfair reputation locally when infact its a great hotel.

Sure there isn't a restaurant or bar but for overall value it does a great job. The rooms are spacious meaning the separate lounge and large bathroom gives it a feel of a appartment rather than hotel. The service is great with the staff always willing to help. The hotel is definitely a business hotel and the shuttle to various HQs is a nice touch.

Happy hour at the bar and free snacks are always welcome
