I moved to Montreal from England and stayed for an entire month and it was the perfect landing spot for me. The apartment could not be in a better location - a amidst endless streets of bars, coffee shops, resteraunts and live music venues. There are several places to get groceries and the Metro is only a 2-minute walk away, which effectively unlocks the city.
The apartment itself is full of history and character - a large victorian townhouse with high cielings and cast-iron radiators. It is a little rough around the edges so if you are a clean-freak or have OCD it might be an issue. If you're the bohemian / creative type it will only add to the charm of the building.
Jen is incredibly friendly and though she only made a few visits to the apartment during my stay all communication and dealings with her were pleasant, reliable and quick to respond. She is not an amateur - she has been doing this for a while.
Overall I would have no hesitation in reccommending this place for travellers, tourists or prospective immigrants like me looking for somewhere to land and get settled.
