I chose to stay at the Comfort Suites Manassas during a recent visit to the area because I was traveling with my dog. This hotel is clean and I saw no signs of animal stains or smells. Overall, I found this hotel to be pleasant, although I must give fellow travelers a few small caveats. Firstly, the pillows must have been designed for the dogs because they are very small, about half the size of a normal pillow. You get four ½ size pillows per bed, but I would have much preferred two normal (human) size pillows. Also, the light in the water closet and the sink area are on the same switch. So, if you need to use the bathroom in the middle of the night, you run the risk of waking others in the room when you turn on the light for the WC because it turns on the sink light at the same time. This problem is easily solved by moving the floor lamp to the bathroom, although you will have to unbraid the cord for the lamp, which like all cords in the room is elaborately braided for some reason. The braiding appears to have no effect on the functioning of the cords. In short, I would recommend this hotel to others travelling in the area, particularly those with pets. All of my qualms are minor and should not overshadow the fact this is a clean, pet friendly, and conveniently located hotel.
