It is in a great location near the airport, and completely safe to walk to and from the airport. I had an early flight to catch and walked at around 2.50am and did not have any issue.
Isabel is very warm and welcoming, and while she didn't speak English, she was more than happy to use google translate. I practiced my broken French to her and it was great fun.
The walls are thin, so you can hear when someone talks in the house. I'm a light sleeper, so I had brought earplugs and it wasn't much of an issue.
