Liv Mtl are excellent hosts- super professional, attentive, quick to respond and very accommodating.
The apartment itself has a great layout, very bright, well stocked bathroom and kitchen, they even include dishwasher pods, garbage bags, laundry detergent, soap and shampoo etc. which is wonderful.
Great for large groups - loads of chairs and sleeping arrangements.
Location is very very very convenient. *keep in mind that also means you hear the busy intersection if you open the windows.
Note that the apartment is on a 3rd floor walk up - with narrow stairs and no railing.
Again- super hosts, and a great place to stay in Montreal- but it is on the pricy side for what it is.
