I stayed there in December for a few nights. The room was clean but kind of dingy and obviously hadn't been updated in many years. The ceiling, for instance, was like something you'd see in your office. I was staying alone, and it didn't bother me, but I'm positive that my wife would have called the room depressing. There was a small fridge, which was helpful, and a flat-screen TV with a decent cable selection. The walls were thin. The breakfast wasn't very good. The service was spotty -- nobody was around when I arrived at about 7 p.m., but I found my key in an envelope on the desk. Combine all that with the residential location in an apparently converted office building on the outskirts of town, and the whole place was a little odd. But the price was very cheap, the place was clean, and the bed was comfortable. So if you aren't too picky about aesthetics or aren't going to spend much time in your room, it might be a good choice. It's a 5 to 10 minute drive into the heart of Boulder, and you might have to pay a two or three bucks to park at a parking garage in the center of town. Again, that didn't bother me much. But if you want to be close to the action in Boulder, this is definitely not the place for you. I've stayed at the Boulder Marriott in the past, and that was terrific but much more expensive. There are some other budget motel options right in town, and I would probably look at one of those next time instead of the Twin Lakes.
