We stayed at Marie-Hélène's place for a month and a half.
The apartment is great, well equipped and we quickly felt at home.
Everything you need to live like you were a local. All services are at proximity (grocery, shops, cafés, restaurants, access to transit and bike share, etc.)
Neighborhood is lively but quiet (except for temporary construction in streets during our stay), nearby parc Baldwin is a nice spot
Communication with Marie-Hélène was clear and quick.
Would recommend this place for anyone looking for a home away from home in Montréal.
