Charles was prompt and detailed in all his communications. Even though he was unable to greet us personally, he arranged for us to have early access to drop our bags. (We had arrived on a cruise ship and were off the ship at 9:30 AM!)
Charles has quite a collection of tourist aids e.g. maps and metro guides, etc. in the living area.
Our room was in the back, away from any street noise and was quite nice. We are probably quite a bit older than the average guests here (I'm 72 and my wife is . . . well not too far behind!) The only reason I mention this is that the bed is very low - about 12" off the floor. a few years ago, this would have not made any difference, but we were able to get out of bed OK, just with a little extra effort!
The bed was very comfy and the room spacious.
When we arrived, the apartment was a little warm so we turned on the air conditioner. As is common in Montreal and other Canadian cities, there is no central air - air conditioning is a floor system with a large hose to exhaust outside through a window adapter. It is a step up from a window air conditioner and soon cooled the main area down. Charles also provided us a small fan which helped immensely.
The living area is very nice and comfortable. Charles provided cereal and several different varieties of milk. There was also material to make a hot breakfast but we are cereal kind of folks so it was fine.
The apartment is in a very nice area just a shot walk from a large city park and a 10 minute walk to two Metro stations (the 24 bus runs along Sherbrooke to and from the metro as well.) There are many places to eat in the area, especially along Papindrau.
On our last evening Charles graciously phoned for us and requested a taxi for transport to the airport. We rarely saw Charles, yet he was a good host and I recommend this place for anyone visiting Montreal.
