Hélène’s apartment in Le Mariais was a great hub for our trip. It fairly close to all the sites of Paris, and if something was too far, there was a metro station just down the road.
The apartment was clean, well-furnished, and stocked with all the necessities.
The apartment is on the street, so opening the blinds is not really impossible. Sometimes the lack of natural lighting would be a bummer, but if one is in Paris there is little reason to be in your apartment very often.
Hélène was also very communicative and helpful. Overall, the apartment was a fantastic deal. I have zero complaints.
