Overall, we had a decent experience with Nicolet's place. The space is large enough for four people, although we only had two. The bed was comfortable, and very little street noise.
However, during our stay, the place was quite dusty. Most surfaces (other than the obvious) had a pretty thick layer of dust on them. Our allergies aren't terrible, but the cleanliness of this apartment definitely agitated them.
Additionally, keep in mind if you are a female, the lighting in the bathroom is very substandard. And the bathroom mirror (the only mirror in the place) is not very tall. Don't expect to see much of your outfit (or even your stomach), if that concerns you. My wife ended up having to drag a floor lamp into the bathroom to get even adequate lighting.
For the price, however, if these issues were addressed, we would stay here again. The location was great, and we had no issues getting in touch with Nicolet during our stay.
