Even that I didn't meet Sean in person he did his best to make sure I'll feel comfortable.
The location of Sean's apartment is next to a inexpensive supermarket, it's located in the center of downtown San Jose, so if you know the area you can walk in the city.
The bed isn't 100% comfortable, but it's not something terrible. the apartment is minimal but the room is big.
There's a small fridge but make sure not to put food in, or else you'll find it frozen in the morning.
the room itself is big, there's a TV, closet, couple of chairs and the sheets felt/looked clean.
There was a parking spot at the back, so no worry about it.

Check the area of San Jose, if you wish to stay in the center, close to the university -> this might be the perfect place for you, while if you wish to be in the suburbs -> think twice about downtown, it's really a matter of preference.

To finalize the summary I can say again that Sean took care of all my needs, however there are some people who expect to pay less and get a really high quality room (hotel's style), I think that Sean's place is perfect if you wish to pay less and still be in the center of San Jose.
