Location is 15-20 minutes from Union (taxi ride from the airport will cost you 56 cad), so you can visit tower and air canada center by foot. Building is easily identified, check-in is very easy due to concierge at the reception.
Clean and cozy, appartment will meet you with tasty bars and more; construction in front of the windows doesn’t sound any, so it is quiet; gym is also available!
So, it is definitely recommended.
