We are so sorry this guest was unhappy! We always strive to make every guest stay as perfect as possible, inspecting every property twice between every departure/arrival. Our staff are human of course, and so even if we hit 95%, that still leaves some issues from time to time for guests to contend with.We manage about 65 properties and not one of them has central air conditioning (absolutely none are advertised as having A/C). Mammoth Lakes is a mountain town at 9000 above sea level. Our hottest days in the summer are in the 80s. It is very breezy here year round. I am unaware of any property other than commercial spaces that are air conditioned in Mammoth. Like a beach town, you just need to open a couple windows.In the event of unseasonably hot weather, we do stock several portable air conditioning units and they can be rented for a delay fee (includes the electricity costs) with about 24 hours notice. Please call in advance to inquire/schedule a rental if you think you will need an A/C unit.Unfortunately, this guest never contacted our office to give us an opportunity to correct any of these issues. If you have trouble during your stay, I encourage you to contact your VR manager while you are in the property, as they may well be prepared to handle your concerns. We have 18 full time staff members in our housekeeping, maintenance and guest services departments who we can call upon to resolve problems. If this happens, or if you are concerned about problems with a unit you are considering, please call our offices at Mammoth Five Star Lodging. We have staff available by phone or email, 7 days/week, 9am-6pm (Pacific) to ensure you book exactly the property you want and to address issues that may come up during your stay. We are happy to help if you will just give us the chance.
