What an apartment. I stayed here for 3 months in the spring and enjoyed the stay immensely. The Paris Perfect crew is very helpful with any queries, the apartment is well maintained and the view is insane (overlooking the famous Place Dauphine and Notre Dame in the distance). For a central Paris apartment this location is very quiet. Everything you might need is within a 10 minute walking distance including great food right outside the doorstep. The balcony has sun from sunrise to 2pm which was such a treat. As a solo traveler the apartment and area felt safe.
The only thing I regret is not extending my stay.
