Christian's place is beautiful - every room has a gorgeous view. The beds were really comfortable after a long day of exploring, the kitchen has everything you need, and the washing machine was an added bonus. The living room has a comfy couch and big tv. While most tv channels are french, there are a few english stations. There is a gym room down the hall (again, beautiful views) with stationary bikes, two elliptical machines, and a stair climber.
Christian was an excellent host - we appreciated his restaurant suggestions and tourist tips (there is a fabulous bakery/cafe a 5 minute walk away). While Old Quebec is close (Plains of Abraham are 2 km away), be prepared for steep inclines. The walk was too far for my parents (in their 70's) but do-able for others without mobility issues. Google maps had lots of parking suggestions close to Old Quebec so we drove and paid (we also went mid-October so parking was available! - not sure what parking there would be like in the summer months).
Christian was a responsive host and answered my questions both before we arrived and during out stay. I'd recommend him and his Penthouse - you won't be disappointed!
