We had an excellent stay at La Maison Clark, and I would recommend it to future guests. We are a family of six (two adults, two young kids, and two small dogs) and it was a very comfortable space with two ample sized bedrooms and 2.5 baths. We never felt cramped whatsoever. The unit itself is extremely modern and luxury hotel room level clean. We used the kitchen and dining area each morning and it had everything we needed. Luc and Charif even stocked some essentials before we got there, which was very much appreciated since the first evening is always a bit of a scramble.
Bedrooms were great. Plenty of space for humans and clothes.
Bathrooms were great - double vanity in master is nice for him and her. One small detail that parents will notice - both bathrooms' shower heads are detachable and can be hand held, which helps materially when bathing young kids.
Onsite enclosed, covered parking is critical. I cannot overstate the convenience of this.
Location is solid. It is extremely close to hot spots (Saint Laurent, Sherbrooke, etc.), but it is located on a small street, such that you are not smack dab in the action, which can be overwhelming. We walked to Old Montreal, no problemo. Quick drive to the Biodome and Mont Royale peak. Saint Catherine is a five min walk away. You will get some street noise on the weekends, but it is manageable, and I am sensitive to it.
Hosts Luc and Charif are A+. I am a high maintenance traveler, and they had me prepped with border crossing logistics, restaurants, kids activities, and cultural events. We were raring to go as soon as we got there.
