I did not meet Helene in person, but her communication with me was quick, respectful, and helpful. She was unable to meet me at the time I needed to check in, so she arranged for me to meet her partner, Stew, a friendly gentleman from the UK.
I'm guessing it's not usually like this, but after check-in I didn't see anyone else in the apartment. The room was clean, the WiFi was fast, and I felt completely comfortable in the room. The bathroom was clean, as was the toilet. I didn't use the kitchen, (which was neat and tidy) but I had the option of cooking my own food there if I wanted to.
The place is not right next to the main attractions in Paris, but it only took me ten minutes to walk to the metro, which gets you anywhere you need to go in in a timely manner. (Took me about 35 min to get to Note Dame cathedral) I felt safe the whole time, but if walking to the metro isn't your thing then Uber drivers are always around.
Seriously, if you're in Paris, consider staying here. Helene and Stew have my highest recommendation. Absolutely can't beat it for the price.
