The two of us stayed at Michelle & Jeff's Airbnb for 4 nights. They were very friendly folks and check-in was very easy (they also responded very quickly with any questions we had on the Airbnb app). The room had all the essentials with a fridge (with La Croix and water), a microwave, and a Keurig, which we used. The double sinks in the bathroom were a plus since there were 2 of us. We also enjoyed the mounted large TV that let us watch Netflix in bed.
The WiFi was a bit spotty sometimes but generally worked. We found that the temperature control in the room was a bit difficult since the house uses central AC, so the room sometimes got too hot or too cold, and it was hard to figure out what temp to set the AC to since it would affect others living in the house.
Overall it was a pleasant stay and we really enjoyed our time in SD!
