After a very frustrating check in (others have said this) that involved an incorrect address and a proprietary app (please make sure you’ve completed all this before you arrive and you will be fine), we arrived at our gorgeous apartment. Only 1 easy flight of stairs up (the elevator is tiny), the apartment was spacious, warm, mostly quiet and had everything we needed. The beds were incredibly comfortable and the showers had great water pressure. The welcome bottle of champagne and the washing up pack were much appreciated. The location on Île de la Cité is convenient: it was a 5-10 min walk to a lovely boulangerie as well as cafés and restaurants. Now that we’ve been through the check-in process, we’d definitely look at Sweet Inn properties again.
