We had a "hotel" room which is kind of a cabin duplex. The room was quite small, but I did like the knotty pine walls, which is something that attracted me on the website. No bathtub; only a shower. The wall A/C unit was basically unusable because it was unbearably loud and old and inefficient. But luckily, it wasn't really that hot, so we didn't really need it. We didn't try the very small tv, but it looked like it was at least 30 years old (I'm not exaggerating. It had a channel DIAL, and I think it was only black and white, not color). The room didn't seem to have housekeeping service since the beds were not made between uses and the towels were not replaced.
But we didn't really mind the fact that it was frankly "rustic". We only stayed there the night before and for three nights after a 5 day wilderness canoe trip. So we didn't need luxury. The porch was convenient for leaving our wet canoeing shoes out so that they would not mildew or stink up our room or our minivan.
My kids enjoyed playing on the swingset near the lake. We appreciated being able to use the freezer in the fish-cleaning house to store a few perishables for our canoe trip. Being right on the lake was convenient when my husband decided on the spur of the moment to book a float plane trip on our last morning when the skies turned out to be beautifully clear. The plane was able to land on the lake and pick us up right at the dock.
The location is nice---on the lake and only minutes from town, and the place might be better for renting a whole cabin if you like to fish or otherwise take advantage of the lake. However, we will probably try one of the in-town hotels for our next trip to Ely.
