Julia was out of town when we arrived but her friend, Julien, was kind enough to wait for us at the apartment to give us the keys and show us her place. He was available for us to contact if we needed anything. There was also a welcoming package with tips and advice for our stay.
The apartment is about a 10-15 min walk from Denfert-Rochereau metro station (there is a closer one but this one is direct from CDG airport). The walk brings you along a cool street (Rue Daguerre) lined with many cafés, meat, cheese, and flower shops. The neighbourhood is quiet and residential, away from the crowds and a relaxing place to wind down at the end of the day. It also felt very safe both during the day and night time when walking home. As mentioned by others, be prepared for the 5 flights of windy stairs.
In total, we stayed for 5 nights. Julia's home has been renovated with modern facilities (kitchen, washer, bathtub/shower) and has everything you would need. Fresh towels and tea and coffee were provided and everything was clean and well-maintained. The water pressure from the shower was great and there's a heated rack for drying your clothes as well. All in all, the photos are an accurate depiction of the apartment and we enjoyed our stay in Julia's home. :)
