Our group of 3 adults (a couple + 1) really enjoyed Sweet Inn. The duplex apartment was perfect for our needs and we recommend it wholeheartedly!
The place: The bottom floor of the duplex has a well equipped kitchen and a living area, as well as a bathroom, a washer closet and a balcony. The kitchen is equipped with a 2-range stove, a microwave, a coffee maker (Nespresso style) a kettle and a dishwasher (no oven). There is a small dining table with enough room for about 3 people, but we preferred to eat in the living area on the low table. There was a medium size TV but we forgot to bring our HDMI cable to connect our computers to it - make sure to pack one. The balcony has views of the nice street below and the beautiful Porte Saint-Denis nearby (apartment is on the 5th floor, building has an elevator). The washer worked great, and there was a drying rack, an iron and an ironing board, as well as some extra clean towels. The host left some washing liquid capsules for us to use. The upper floor has two rooms, one with a double bed and one with a single bed, both furnished with dressers, a bathroom with a bath, as well as a small storage space with some more equipment. Heating was available downstairs, in the rooms, and in the upstairs bathroom. The internet was ok, but not great - we sometimes had to use our mobile hotspots to make video calls.
The location: The apartment is perfectly located, close to busy commercial streets, and walking distance to the Pompidou and other landmarks. There is a metro station close by. We enjoyed walking to Rue des Petits Carreaux in the mornings for groceries and pastries, as well as Rue du Nil for cheese, and staging breakfasts in the apartment to start off our day.
The logistics: When booking this place you'll be asked to leave more information on the Sweet Inn website and make a security deposit by credit card. We scheduled a check in in advance and communicated with our host through whatsapp to let them know exactly when we'd arrive. The host met us at the apartment to show us around and hand us the keys (one set of keys). At checkout we just left the keys on the table and left (the door cannot be opened from outside without the key). The security deposit is promptly refunded once they confirm everything is in order.
In summary, we really enjoyed the convenient location and great apartment, and are very pleased to have found this place at such a reasonable rate.
