What a great place to stay! A few of us came here for a conference and loved the place. Dan and Sophie are great hosts, incredibly responsive and accommodating. We were arriving at different times, but they made it easy to coordinate check-in. The place is just as cool and charming (if not more) as the pictures, with plenty of room. It has all you could need (linens, toiletries, towels, full kitchen). The terrace is amazing, and the shower is one of the most satisfying ever! There are 2 bedrooms, 1 beautiful king bedroom that's on the busy, bustling side of the place (awesome if you want that city feel, not recommended if you're sensitive to noise) and another lovely bedroom that's on the quiet side of the place. We were there during a bit of a heatwave, and then also when it cooled off, and the temperature there was very comfortable (there are fans, AC, and heaters).
In terms of location, it's right above the famous Schwartz deli, so can't go wrong there! It's on busy bustling St. Laurent, full of shops, restaurants, bars, clubs, and other things. It's a great location, probably walkable to many places (for example, it was a 20min walk to our conference convention center, also a comparable walk to Mont Royal, etc). And, if for whatever reason, you end up staying in, there's foosball, a lovely dining table to eat at, television, terrace to hang out on, etc.
