This place is an absolute gem. The location is unparalleled - steps from the lake (which connects with two other lakes. We were here for 5 weeks this summer and took advantage of being able to do morning walks, rent bikes and kayaks, and swim at the beach. The house is located just a few blocks from amazing restaurants, coffeshops and bars. There's an exceptional grocery store just a few blocks away. You can't ask for a better walkability score for a place.
As far as the place itself, let's just say that we didn't really want to leave. The two words that come to mind when thinking about this place: classy and comfortable. Really nice touches all around - amazingly comfortable beds, thick, hotel-quality towels, great bedding, nice floor rugs, and really nice furniture. The space is laid out really well with big open rooms and lots of natural light. We really felt at home and were so happy that we picked a place that was so nice and comfy. The tenant downstairs is very nice, offered many times to let her know if we needed anything, and was very easy going.
Nancy is amazing host. She strikes the right balance between being available/responsive but is not at all intrusive. She is super warm and we loved getting to know her.
In short, you will not be disappointed with this place. The location, the amenities, and the place itself is topflight.
