Eric's communication and check in instructions was very clear and easy to follow. Likewise he ensured the place was available soon after our train arrived so we could drop off our luggage as soon as we arrived.
The apartment is located very centrally and close to a few metro stations (within 5 - 10 minute walk).
One thing to keep in mind is that there is a very narrow staircase up to the bedrooms (as tends to be normal in Paris) - something to keep in mind if you have large suitcases. Likewise the bathroom is only accessible via one of the bedrooms, so not ideal if you are travelling with light sleepers!
