I stayed with David during a relocation, and am already planning to do so again as I finish my move. He is polite and responsive, and the spaces he hosts guests in are clean and private.
The outstanding characteristic of his house is how quiet it is, especially in the lower section where I stayed. If you're bothered by airport noise, this is one of the best options in the Twin Cities. It's doubly-impressive because it's located halfway between Downtown and the airport, convenient to many of the best restaurants in the Metro, and yet is quieter than the La Quinta Minnetonka. The walls are thick and well insulated, and the house sits on a slope that shields the side facing the airport from noise.
It's also quite spacious. I've stayed in a studio suite at the Westin and the Spectacular Room at the W, and it's bigger than both. (It might even be as big as both of them put together.) There are two large walk-in closets, two bedrooms, a private bathroom and a kitchen and living room joined together with an open floorplan and surrounded by windows.
The L-shaped couch in the living room is larger than it appears in his photo. I'm six feet tall and could lie down on it with room to spare.
Both the bathroom and kitchen were commendably clean. In the latter I found a fruit bowl with several Honeycrisp apples and a half-dozen just-ripe bananas, which was a nice touch. There were a few staples on shelves nearby, and I was able to use others from the kitchen upstairs after asking David.
The house is located in Linden Hills, which is one of the nicest areas of Minneapolis. You can easily walk to the northwest side of Lake Harriet and the south end of Lake Bde Maka Ska (formerly Lake Calhoun). The biggest danger in doing so on a late summer night is that there might be too many other people out doing the same thing. (I know because I grew up just a few blocks to the south.)
I didn't test the internet hookup, but there is a WiFi access point within ten feet of both bedrooms as well as one ethernet line to each. Both are connected to US Internet fiber (100 megabit, according to David), which I know from previous experience to be very reliable and every bit as fast as advertised.
This was my first experience with Airbnb, and it was awesome :)
