Le Garage was fantastic! I've been travelling around Canada for a few weeks and stayed in a number of air bnbs and this is by far the best. The place is exactly as shown in the pictures with everything you might need - fridge, kettle, microwave etc. Lyne left pastries, water and beers and was easy to communicate with and very pleasant.
We didn't have a car but found transit to get downtown/to the old town very easy - just one bus ride and you pick the bus up one block over.
I would highly recommend a stay at Le Garage if you are in Quebec City - a truly unique place to stay!
