Had a wonderful stay at Tiffany's. She was very accommodating of our bags being left in the common area prior to/after check-in/out and communication was great. Don't let first impressions of the entrance fool you - although it enters off an alleyway, it is safe and within view of the restaurant across the street.
As others have said, the location couldn't be any better for being less than a 3min walk to Jean-Talon station, grocery/convenience stores, and within walking distance of bars and cafes.
The interior is accurate to the pictures and has much of what anyone would need for a weekend stay. AC/tv/wifi works flawlessly and the unit is very spacious for 2 people.
Light sleepers and sound-sensitive people take note that Fri/Sat evenings are the loudest with the bar below but Sun/Mon are quiet as it is closed then. The showers are lukewarm at best but I'm used to taking cooler showers so not an issue for me. Anyone with ambulatory concerns might want to also want to be aware that you will have to navigate a flight of narrow stairs to reach the 2nd floor where all 3 units are.
Would definitely recommend staying here if any of the above concerns don't bother you one bit and would stay here again if given the opportunity.
