Tania's apartment was absolutely great. The pictures do not do it justice, as it is much larger than expected. There is also a small deck/outdoor seating area not pictured. The location of the apartment is also great - It is just off a major avenue (Avenue du Mont Royal) making it easy for first timers to the area to locate it, and we were able to walk to most of the other neighborhoods we visited. For the few locations that were too far to walk to, the metro is short 8 minute walk, and busses run on the avenue. Don't be concerned about noise from the avenue though, the apartment is just far enough from the Avenue to eliminate any noise concerns, and the bedroom is the further room from the street - we did not hear a peep at night.
Tania was very quick to respond to all communication. When the app to open the door was not working initially she quickly unlocked it for us remotely. She was also very helpful in explaining the idiosyncrasies of the street parking rules (and definitely saved us from a costly ticket). The one note is that the wifi did not seem to work well in the bedroom, but this had no negative impact on our stay. We will absolutely book Tania's apartment again the next time we come to Montreal.
