Disappointing experience
Travelling round the world in a lot of 4* and 5* hotels I truly can’t understand why the Westin Cadillac in Detroit is such high-rated at Tripadvisor. It was a disappointing experience from check-in during the stay and also checkout. 
Check-in: I reserved a room with King bed months ago paid with SPG points. Receptionist wasn’t able to find the reservation. Than we got the keys and went to our room. “Surprise” is was with 2 single beds.. Went down to the reception again and requested the room we reserved with king bed (or at least ONE bed). It took a lot of time – be aware we arrived from Europe after 10hour flight and approx. 15hour travel time in total – and we just wanted to get to the room and relax. So we waited again at the bar and the guy from the reception brought us the keys for the new room – upgraded to club level. Sounds good but was not. Smelly floor, small and dark room with “view” to the opposite wall. We decided not to change the room again (reception guy was not friendly at all and because we already saw 2 rooms the hope that one would be better was gone) and better to leave the other day and look for another hotel. So we checked out after 1 night at the Westin instead of 4 nights as planned. Reception wasn’t interested in knowing the reasons why we are leaving earlier – again not very friendly attitude. At least SPG got me some points back – but also paying for 1 night is one night paid too much.
