We went down to SD for my birthday weekend. Overall we had a good stay. Everything was clean and location was good.
Just a few things to note (not necessarily negatives, but helpful to know):
1) This place is really small like other reviewers have mentioned. It's essentially a studio and you are steps away from every part of the room. It's listed as a "tiny house", but I wouldn't consider it that. A lot of the pictures were taken up close so it's hard to gauge...it's TIGHT.
2) You can't control the thermostat. Unfortunately one of our days we were in SD, it was really hot (almost unbearable). We came back midday for our son's nap and we were all really uncomfortable. Cynthia then messaged me that the AC was broken which was really unfortunate. She offered an extra fan, but it honestly would've just circulated warm air around.
3) My husband and I both felt the bed and pillows were uncomfortable. This could be based on preference though!
