Lovely place. It is a LONG way up the steep stairs (just beware), but a super place to stay. Kitchen is well-quipped, nice bathroom, comfortable beds. The A/C unit is in the hall, so bedroom doors open for sleeping in the summer. The back porch was a great place to sit for a mean, as was the dining room table.
Ave Cartier is a great street but it’s really also worth a walk over to Rue St-Jean, with hipster shops and restaurants, and even a community fridge in the street. The Musée des beaux arts de Québec is a beautiful art museum on the Plains of Abraham and just a short walk away too. You can walk the whole city from Simon’s place, for sure. Wonderful 4 day stay in Québec City for sure.
