Is Uber or Lyft readily available? I am interested in bot airport to a centrally located hotel or VRBO and also around the city?
Uber operates in Montreal. Also, it is normally recommended taking the taxi from the airport to the Montreal's city center. You can also take the metro and the bus to go around the city. Montreal's public transport is very well connected.
There is an express bus that is integrated into the rest of the transit system, $10. Also, read up on the legality of vrbo properties. I suggest reading previous discussions about airbnb.
