Highly recommend your staying in Emmanuel’s flat for your time in Paris! Like you, I rely heavily on reviews/comments when booking an AirBnB, and all the more when visiting a foreign country where I don’t know the area AT ALL! Emmanuel’s flat is in the Lê Marais district, which felt very safe, with many shops/restaurants nearby, and just a few blocks from the metro station. This flat is a good way to really experience Paris, especially if you take the metro, cruise around on Lime scooters, and enjoy being more than a tourist but a tourist among the Parisians! The flat itself isn’t fancy, but it looks as shown in the pics, and gets the job done. We mostly ate at restaurants, until the final night when we bought food at a grocery store and cooked at home. It was nice to have that added convenience over a hotel - the kitchen is stocked for your basic cooking needs. We didn’t have the chance to meet Emmanuel, but a colleague of his staying next door welcomed us and showed us around the place. The flat is very safe, separated from the street by a locked gate with a code, then a small courtyard with a locked door, then up three flights of stairs to a locked door to his two flats, then a locked door to the flat your looking at. Lots of locks, not because it’s unsafe, but just because that’s the setup (seemingly for many similar flats in Paris). We stayed out late (for us!), and felt fine walking home. Wherever you stay, enjoy Paris!!!
