Properties over the years have changed. Used to be a house that was lived in and maintained by the owners. Now it is more of a business, so the place is cleaned up, fresh towels and bedding, but no longer the feel of a home. Little things that break or wear out in our homes are constantly replaced and repaired. No longer the case. These are things that most people won't complain about. Weather it is an old drawer or cabinet that no longer closes great or squeaks, loose tiles, old things like coffee makers or utensils or other kitchen wear or furniture. The quantity is there, but no longer the feeling that someone who cares is keeping it up. Why spend the money to upgrade if we keep getting 5-star ratings? I find this the case with most properties these days. They are fine, and serve the purpose, but the prices have gone way up while the effort to keep it up and upgrade has gone down.
Yes, we had a good time, and it served the purpose, but I've stayed in places where things were constantly upgraded, and they provide a better overall experience. May be if we stop automatically giving 5-stars to everyone who does an adequate job, we would put more pressure on the owners to invest in the improvements needed.
