I stayed at Elise's place with five colleagues for a conference. Her place is about a 20 min walk to the downtown core and is super close to great restaurants, vieux Quebec, the touristy spots and the nightlife. The place was also really clean, comfortable, and had a great aesthetic. The check in and building access is also very easy. Elise was prompt and helpful for all the questions we had.
We had 6 people in the place, and with all our suitcases there it was a little cramped. 5 people would have been ideal.
Fyi for any fellow gym rats - the gym in the building does not have any weights or cables, just cardio.
