While I understand the sentiment of your question about private feedback, I also understand why a guest would leave such suggestions in the private feedback. Your example of buying a Nissan is a bit off-target because your renters are not buying your space; they're renting it. To that end, a better example would be renting a car from Enterprise (or similar) and then returning the car and when they ask how the car was (because that's what the Private Feedback is doing: asking their opinion), you state, "I really enjoyed the car, but it would be great if you offered one that had reclining seats in the back." While Enterprise might not rush out and buy a car that has reclining seats in the back, they may keep it in mind the next time they're stocking up inventory... especially if several customers have made the same comment. And, they might also just ignore the feedback because they think it's not necessary to offer that amenity. It becomes their decision, but at least they're aware of what customers are thinking.
For me, I've used some of the Private Feedback to make improvements, such as adding a dedicated desk/chair, but I've also ignored some, such as blacking out our two ceiling-level windows. I've also done a fairly decent job of anticipating requests because some of the Private Feedback included items that were already on my "To Do/Add" list.
For the Keurig, I find it to be a completely reasonable suggestion... probably because we offer one. It's acutally not messy at all, as long as you don't offer the make-your-own-coffee pod. An expense? Sure. But we only offer two pods per person per night and the average use is probably one pod per reservation (not person/night). We buy them at Costco for about $0.50/pod, so even if they used all of them, I'm only out $2/night. Add in non-refrigerated creamer and sugar costs and it's MAYBE $3/night. And that's before tax season, where I can write off my coffee maker and all the supplies associated with it.
But, here's the kicker: 99% of hotels offer some sort of coffee for their guests. If you're not offering coffee, you're actually offering less than a hotel. Sure, you might be cheaper, but even the ridiculously cheap hotels are now offering coffee... because it's such an insignificant expense compared to having happy guests. Offering a Keurig, however, not only puts you on par with hotels offering coffee, it actually makes you BETTER because very few hotels offer that level of coffee. So, a $90 coffee maker and $3/night (worst case) of supplies will keep your prices less than a hotel, but make the experience significantly better than a hotel. Food (or coffee?) for thought.
