Wow, such a great place. We stayed with our young daughter and it was a great vacation. The building is one of the best in the area, the loft itself is large, sunny and we loved it. The location can't be beat, its close to everything in the Old Port, but its quieter at night than some spots closer to the 2 main streets (St-Paul and de la Commune). We had no trouble sleeping.
Get ready for some stairs on the way up (free exercise!).
The host was always available to help us when needed.
