Marine’s place is located in a central part of Paris. It was really easy for us to reach most of the attractions and other neighbourhoods by walking. And there is also a few metro stations 10-15 min. away. Cafes, bars, grocery stores, bakeries are all around in a short walking distance.
The building is really old, with wooden stairs and ceilings. But I think Marine did a good job inside the apartment. Kitchen, bathroom, water pressure/warmth etc. were good.
She is a considerate and responsive host. Checking in&out with lockbox was also very easy. I would definitely recommend her place for couples or singles for short/long term stay, especially if it is your first time in Paris. It was easy to orientate ourselves. Have fun!
