1. Stay at the closest airport to YOW, Holiday Inn, Hilton, etc... You can get there probably with a shuttle that most airport hotels provide (ask for it). There is nothing spectacular to see in in this area. Good place to sleep.

2. And what I would suggest...take route 97 to downtown airport, cost: $4 (takes around 40 minutes), or take a taxi, cost: $25-30 (takes around 20-25 minutes). It's safe, sunset is not till 9pm or later, and people are usually walking in the evening with the warm weather. Walk around Parliament Hill, etc..., stay somewhere downtown. Take taxi in the morning, not sure if OC Transpo (Ottawa transit) operates at 4am.

Either way, you would have to head back to the airport by 4-415am.
