We stayed here for two nights total in October 2011 - one night each at the beginning and end of a week-long San Francisco area trip. The main advantage was that it was within a couple miles of the airport, which was nice since our flight arriving in San Francisco was almost 2 hours late and we didn't get in until around 10pm. All onsite parking is in a basement-level garage, and the spaces looked pretty small. Fortunately, on the nights we stayed there, it wasn't packed. The rooms were pretty basic with reasonable amenities. The bathroom had just the toilet and tub, while the sink/vanity area was in the main section, a layout that turned out to be very common in the places we stayed in the area. It would have been nice to be able to close the thick curtains, which apparently were just there for window dressing - there was only a thinner white curtain that could cover the window. The general condition of the hotel made me think that it had seen better days, although it was certainly clean throughout. On our first night there, our room was fairly close to the street, so we did hear a bit of road noise with some busses and trucks going by. Also, on our last night there, I tried to print out boarding passes for our return flight, but the printer was out of order; it turned out to be no big deal but could have been an incovenience. We didn't do much in Millbrae, but it seemed like a nice area, with several places to eat and a Safeway nearby.
Overall, this hotel served its purpose - to give us a convenient place to stay near the airport. Depending on the rates, if I were staying in the area longer, I may consider looking at some of the other hotels in the area, as there were several on the same stretch of road.
