Everything was perfect except had an issue with booking through Hotels.com. I booked a room with king bed and a pull out sofa for three people. When I got to the hotel, we got a room with only a king bed. Lucky a suite was available, if not it would be horrible. And though I indicated 3 people at the time of booking, I was charged extra for a third person.
Hotel is very conveniently located in the Byward Market area. 10 minute walk to the Parliament. 5 minute walk to Rideau Centre. Parking is limited at the hotel and you have to pay for overnight parking.
