This loft worked great for our family of 4 with 1 bed on the top floor and 2 pull out couches. The location is terrific with easy walking access to the lower part of the city as well as the main plaza and streets near the upper city and the Chateau Frontenac. The check-in is about a 4 minute walk from the apartment, at the Hotel Sainte-Anne (thankfully all downhill). Be prepared to walk up 3 flights of stairs with your luggage.
The loft's patio is the BEST place in the city to watch fireworks over the river (Thursday nights mid-July to early September)! Wear shoes on the deck to avoid splinters.
