Good value choice near the airport; better than the other airport Marriott Courtyard
I have stayed at both of the Marriott Courtyard hotels near the San Antonio airport. The one near North Star Mall is a better location and the better of the two hotels.
Reception staff are friendly and helpful. Parking is convenient and usually sufficient (though less easy if the hotel is full). The location might work for tourists with a car, but is really best suited to travelers who need to be near the airport or who have business in SA. It is not ideal for tourists wanting to be by the Riverwalk or the Alamo.
The room was clean, comfortable and a good size. The bathroom is OK. Waterflow to the wash basin and the shower is not too powerful, but when I mentioned this to the front desk I was told they have installed flow regulators and the regulator can be removed on request. 
The breakfast buffet has usually been standard fare. I did not try it this time, but I expect it was OK.
If the location is convenient for your needs, then this hotel could be a good choice. It was excellent value for the cost on this occasion. I would certainly stay here again.
