My girlfried and I spent a week at Lingling's patio and we truly had a great time. The location was as advertised -- close to the city centre as well as to the metro. While for the majority of the time I attended a conference (20 min walking distance), my girlfriend explored Montreal throughout the day, which was likewise possible by foot. Despite the central location, the patio is situated in a quiet side street with a beatiful little garden, that can directly be accessed via the patio's terrace (a couple of birds and a cute squirrel payed us a visit once in a while). The place was very clean, we could take a good shower and the bed was extraordinarily comfortable.
Lingling was (without exaggeration) a truly amazing host -- always reliable, approachable and eager to help out with recommendations and tipps for going out, while always respecting our privacy. Upon our arrival, she left us cute little notes with helpful instructions and a personalised map, which we found very helpful. At the last day of our stay, she blocked us a parking spot with her car, which she re-parked when we arrived with our rental for our onwards journey. Bottom line: We can only highly recommend staying with Lingling and will definitely come back should there be the chance!
