TripAdvisor Reviews: 

1. “We liked this hotel for many reasons including its excellent location. We were in Paris in late Dec 2019 during the rail strikes but that didn’t impact us as the hotel was walking distance to wherever we wanted to go including the Louvre, Musee Orsay, Saint Chapelle, Notre Dame Cathedral (under repair at the time of our visit). It is also walking distance to the Chatelet-les-Halles Metro station and a major Westfield Shopping Centre.”
2. “Can’t top the location! While we were initially surprised at the small size of the apartment, we quickly came to appreciate what this efficient apartment does offer: nice view, comfortable bed, easy walking distance to most of the attractions we wanted to visit including the Louvre, Musee Orsay, Saint Chapelle, Notre Dame, City Hall, and the Latin Quarter and at a price that is much lower than the hotel next door that doesn’t have kitchens. The metro is just steps away as is a huge shopping mall, wonderful park, and bistros that come alive at night. The staff was engaging and helpful once we reached out to them, especially Alejandro, Samara, Clovis, and Sena. A grocery store is just steps away as is Saudade, an attractive restaurant with welcoming owner and staff, especially Alejandra, who specialize in excellent Portuguese cuisine.”
3. “Rooms a little small. Not much space for luggage. Sofa bed takes up entire living room. Location.”
4. “The shower! If you like your shower hot, good luck to you. The water was like warm at best. The locations was amazing and the room was large and renovated.” 
5. “Despite major renovations taking place at the property we had a great experience and our room was very clean, spacious and well fitted. The staff were very friendly and helpful and the property is located well to explore Paris on foot or from nearby train station.”

Enjoy your trip!
