A great space for a low-maintenance solo traveler. The space is small, clean, walking distance (<1mi) to most attractions, easy access to the metro, and reasonably safe. It would be very snug for 2 adults, and likely not comfortable for a larger-framed person (my husband wouldn’t have been comfortable with the size of the bathroom/shower). As far as safety, I felt totally safe in the apartment and generally in the surrounding area. The neighborhood is lively and a nice break from tourist areas. I preferred entering and exiting from the gate across from Le Sully. The passage gates are locked overnight and on Sunday. I did have a man follow me while calling to me from the Passage du Prado gate (opposite end from Le Sully) and into the metro station in the early evening on a week night. Just keep your wits about you and be aware of your surroundings - same as you should in any city. Daniele and Antoine were very helpful in the days leading up to my trip and were able to do an early check in. Daniele recommended Bagbnb to find someone to hold my luggage until the apartment was available, and the hotel in the passage was one of the options, very convenient.
