I have stayed at my fair share of airbnbs in Paris over the years, and Alex's apartment next to the Opera was by far the most enjoyable. On the top floor of a beautiful building with an elevator, the apartment has been fully renovated to expose the ancient structural rafters and add depth to the rooms. The charm is palpable. There are multiple skylights and windows everywhere that bring lots of natural light into the apartment, not to mention the balcony that extends the full length of the apartment where you can get direct sunlight all morning. The apartment is very spacious, as listed in the description, and the bathroom is amazing with the largest shower I've seen in Paris. Alex keeps the apartment super clean so not recommended for messy people. Otherwise do not hesitate you will have an amazing stay. The closest metro (4 Septembre) is literally 20 steps from the entrance.
