Stay at the Marriott residence inn instead of here!! The air conditioner broke the first night of our stay with Denver having almost degree days! They could not fix it so we were left paying over $200 per night for a hot, hot non-air conditioned room. They brought in this giant fan thing which did not cool the room down and we had to use it to blow in cold air from the hallway until we went to bed. We have asked for 50% refund (which we think is quite reasonable considering, feel we should get full refund) but they are refusing. Also, note there is no elevator and you will have to carry your luggage up three flights of stairs, as we did, in a very hot, non- air condoned stairwell. We have had good luck with Airbnb in the past but this was unacceptable. Sonder started out as very customer service driven but this was so bad. Stay at the Marriott, same neighborhood, can handle a service problem, free breakfast, pool and bigger spaces. Wish that I had done more research and stayed there instead.
