GMC renaissance center
This hotel is very nice!! The king size rooms were smaller. The house keeping was not on point. I had taken some dishes from the concierge lounge back to my room and it took them 2 days to clean them up. They left the newspapers in my room. They also left my room service plate in there for 2 days. 
This hotel was really nice it felt like a maze walking around. The architecture was really fun to look at. I also liked looking at all the Chevy, GMC, Cadillac vehicles that were on display. This is really one of the best hotels in Detroit.
The Concierge lounge mon-thurs was super packed in the morning. At night it felt like a club where there was a lot of singles trying to hook up.
