We stayed at Karla's place for almost 3 months while in Moncton. Karla is a wonderful host, always very quick to respond and address any issues we had. Provided us with a vacuum when we requested as well as fixed some small issues with the bed.
Karla's place was nice and in a good location - on some bus routes as well as a 25 minute walk to town. The apartment was fairly well equipped with kitchen utensils, cleaning supplies etc. Beds were comfortable - a spare set of sheets would have been appreciated. The apartment is spacious and was nice for our family of three.
The walls are quite thin and very often we could hear the neighbours talking on the phone and hear their TV quite clearly. Footsteps from upstairs were super loud as well. If you are a light sleeper or sensitive to noise I would be aware of this - earplugs helped in the night, but often we were woken up by footsteps or noises from above or below in the night/morning. The neighbours weren't particularly loud, just very poor insulation in the walls. We also had some problems with the wifi cutting out which Karla did try to help with, but it continued to be spotty. As others have noted the laundry is shared in the basement and is paid, but we never had any issues with it being busy when we needed it.
Overall I'd recommend Karla's place as a god option for Moncton and she was a great host always happy to help!
