I stayed in Gary's cottage for a week with my young family (wife, 5yo, 3yo, 1yo), and overall it was great. Plenty of room, a fantastic pool area for the kids to enjoy, and a near perfect location off of Magazine for those wanting to visit New Orleans and not just the FQ. Only two things I'll note:
1.) The pictures of the main floor and pool don't do the actual property justice. If you're impressed and considering this place just on the first floor pictures alone, like I was, go ahead and book — it's going to be better in person.
2.) The upstairs is comprised of a fairly tight full bath at the top and two sizable bedrooms. The stairs leading down are decently steep and have a fairly abrupt start to them (i.e., there's not much of a "hallway" at the top; you kind of walk out of the room and then carefully step around/over the stair opening). If you've got young kids, it's a panic attack waiting to happen (we ended up not using the upstairs at all during our stay out of fear one would fall down them). If you've got professional partiers on your hands because "I'm in NOLA, whoooooo," then the warning still holds true. Add in that the upstairs is a bit claustrophobic and slightly creepy with its angled ceiling and mounted mirrors — completely subjective, I know — and let's just say that I would absolutely pay a good amount extra to take the downstairs masters if I was splitting this place with a group of friends.
All of that being said, this place is fantastic and Gary was super easy to work with. I hope we get the chance to stay here again in the future.
