TL;DR:
Mabel's place feels like a true, authentic AirBnB - it's the apartment she and her family live in, and that's what makes it wonderful. Though the apartment was a little less organized than the pictures show, we still felt right at home from the moment we walked in, loved both our time spent there and the incredible neighborhood its in, and would gladly stay there again.
PROS:
My girlfriend and I shared the place with my parents, and there was *plenty* of room. We mostly spent time hanging out on the very spacious terrace and in the kitchen, and also used the upstairs sitting room once or twice. The kitchen was fully equipped, and we were even able to cook a fantastic meal on one night of our stay - a rarity in my AirBnB experiences. There wasn't much room in the kitchen fridge (just one small shelf was available for us), but the full-sized fridge upstairs had more room. We kept food and some beer downstairs, and more beer upstairs, and that gave us plenty of space for what we ate. With the exception of one night (a Friday) when the next-door neighbors stayed on the terrace talking until 1 a.m., the apartment is beautifully quiet and easy to sleep in. Also, the location can't be beat. It's around the corner from a huge selection of brunch spaces, restaurants, bars, and shops, and the transit connection is ideal. A wonderful section of old canals is just a few minutes' walk away, as is the Albert Cuyp market.
CONS:
Both Mabel's WiFi and our cell phone reception were spotty inside the apartment, so we were all glad not to need much internet access while we were home - if you're planning on working remotely, or streaming lots of movies at night, you might be disappointed.
