We could not have been more pleased with Marie's flat. It was our first time in Paris and the location allowed us to walk nearly everywhere (the exception being Versailles) and allowing us to see all of the major sites on our checklist. To be clear, we enjoy being on the ground in new locations, so walking 3-5KM (1.5 - 3 miles) one way isn't an issue for us. That said, public transportation is very close, within a couple minutes walk depending on what you are looking to use. There are metro, RER and bus stops all around the location. You will have complete access to the city if you stay at this location.
This was also our first AirBNB experience, so we did our research on the various locations to stay. All of the information that was supplied by Marie was accurate and, if anything, was a little modest. The flat was clean and well appointed. We used it primarily as a home base so we left in the morning and returned at bedtime. However, there was more than enough space, materials, and access had we wanted to stay in and make a meal and enjoy the views of the garden and street activity. Anything you need to cook was included in the kitchen space: pots, pans, glasses, a small cooktop, microwave, coffee maker etc.
The bathroom was clean and had everything we felt it needed. The water pressure was good, sinks and toilet worked without issue. Towels and hairdryer were supplied as well as essentials like toilet paper and drinking glasses. We brought our own toiletries, but there is a convenience store within a block that had whatever we might have forgotten. Essentially anything you would expect from a nice hotel was there for our use.
Finally, Marie and her husband are lovely, kind and were extremely helpful as we prepared for our trip and arrival. Marie was not able to meet us personally, but Sheila (and her husband - both also very nice), a friend of Marie's was there and waiting when we arrived. We got a quick lesson on the keys and a rundown of the space, and we were settled and ready to enjoy Paris!
Overall, the process from beginning to end was easy. We were a little nervous as we had never used AirBNB before, but Marie sent occasional notes, gave us clear arrival instructions and the flat was very much as advertised. There were no surprises. We could not have been more pleased with the flat, the location, the access or with Marie's hospitality. Our hope is to get back to Paris and contacting Marie will be the first item on the checklist for our next trip.
