We had a great stay at the Cadet Residences, and would highly recommend it. It has a sort of "hotel" vibe. We had a ground floor unit which was very convenient, and felt very secure. It was spacious and well-equipped, and Philippe at the front desk (who was there most of every day) was super helpful and friendly (and his English is great). The kitchen was well-equipped, the air conditioning welcome, everything was very neat and clean, and we loved the location on rue Cadet. It's just a couple of minutes from the Cadet metro stop. Lots of restaurants all around (our favorite was the Petit Cadet -- great food, great staff, great people-watching), as well as several bakeries and a pharmacy. We took the Metro all over, and It was also an easy walk to Sacre Coeur (or at least easy until you get to the hill itself). The free on-premises washer and (separate) drier were also great, as was the wifi. Did I mention that Philippe was great? He also made restaurant recommendations, and reserved a taxi for us the night before we left, when he heard we would be leaving very early. All in all, a great place and great staff.
