We contacted with Samuel via Airbnb app, he always responses very fast. When we asked Samuel about additional items that we needed(the heater, blanket, hairdryer, blender) he answered always positively and the next day we already had what we asked for. We had one concern about cockroaches, but he called the specialists(even twice) and tries to do his best to help us. All in all the stay with Samuel was perfect. The location is excellent for students from Concordia.
