Valentina's place is on the first floor of a typical Verdun circa 1920s walk-up building with six units, located right around the corner of Wellington street with its numerous stores, cafés and restaurants; I personally recommend Café Baobab, Well, Salon de Thé Cha Noir, HoniHoni and Copette in particular. You can also easily catch bus 58 or 61 which will take you to De l'Eglise metro station, though it's easy enough just walking there or to Verdun station.
The apartment was evidently renovated recently so you get the charm of the old architecture with modern comfort (though I did sort of miss those creaky hardwood floors!). The kitchen has everything needed to cook your own meals, storage space is provided by several built-in closets, and there's a large flatscreen TV with access to Netflix. Valentina herself was always very responsive and helpful.
All in all a great experience and I'd definitely recommend Valentina's place :)
