First things first, make sure you're okay with a shared room. I was, my two traveling companions were not as happy. For the price, this is a good enough airbnb. It is sort of like a hostel where many people are staying at the same time. My only complaint is the room kind of gets stuffy at night because there isn't really A/C. Also, if you're last to book, you can't get a fob to enter on your own so you get a midnight curfew. Again, I was fine with all of the above for the price of the room. We had a great trip and visited a lot of places because of the central location.
I think I mostly interacted with the host's daughter. She was very kind and spoke a little English. We would use french and English to communicate. She was quick to respond to messages and very helpful.
