My stay at The Onyx Apartment Hotel was quite a mix. The location was fantastic, right next to the CTICC and close to everything I needed, but I had some issues with noise from neighboring rooms that kept me up at night. The spacious room was nice and clean, but the spa experience left something to be desired. Overall, it was good but not without its hiccups.
