I had a really good stay in Montreal for almost a month during October - the apartment is just like the pictures - spacious, a good kitchen where I was able to cook some nice meals with food bought at the local shops and the wonderful marche Jean Talon. The apartment is close to a really nice park - Parc La Fontaine - and i found that the nicest way to travel around was either to get a hire bike from the rank opposite or to walk through the park to Sherbrooke metro, which took about 25 mins. The streets around Duluth and St Denis (15-20 mins walk) have lots of good place to eat, coffee bars, small shops, yoga studios etc.
Carole was a great host - communicative before the visit and swiftly responsive to any queries. I'd definitely recommend to a single or couple for any length of stay, 4 people might feel a bit cramped if staying for more than a few nights - though probably fine for a young family. Thanks very much for your hospitality
