Choosing
The downtown filter, stated plainly
The downtown search is a location filter. People who add it are usually trying to keep Peel, Place des Arts, and the winter indoor network inside the plan. That is a sound filter. It does not tell you which building has a quiet room this month. Take the filter to a travel provider after you know which corner of the grid you want, and ask there about noise, walk times, and any indoor connection.
Old Montreal remains the historic alternative, covered on its own page, and the Plateau remains the neighbourhood alternative. A dawn departure still belongs with the airport guide. DVSVC can help you separate those maps. It cannot hold a downtown room or tell you that one tower is the one to book.
