If you've never been to Quebec City, Saint-Roch is the neighborhood to be in. Rue Saint-Josef is packed with cocktail bars, microbreweries, micro-roasters, cafes, restaurants, a Metro grocery store, and is right on several bus lines that go out to Limoilou and the Grand Marche or up the hill to Parliament and Montcalm. The chalet here is right on a main thoroughfare while still being quiet, as the condo faces away form the street. Flexible check-in/check-out with clear instructions for the coded door(s) was also great.
So why not a perfect five stars? For the price, the host doesn't provide competitive services to a hotel: request to buy not only your own shampo and wash (which is a strike), but even toilet paper. The supplied amenities are weak. Also frequent communications, and the feeling of pressure to review or extend stay - just let me relax on my vacation.
We didn't have kids, but the condo was kid-friendly: supplies, toys, games, highchairs, even a playpen tucked in a closet.
