Erick's place is pretty accurately described in his listing and by previous reviews. Upon arrival, the space may seem a little smaller than the pictures, but it is a practical and sufficient size for one to two travelers on a short stay.
Some reviewers mentioned the stairway is narrow. This is true, but what is more concerning is that it has no lighting and the worn wood is slippery. I did not feel entirely safe using the stairwell at night. Thankfully, I had packed a flashlight and also used my cellphone to check the stairway before use, and also make sure I did not slip. I suspect this is a building management issue, and may not be within Erick's ability to change. But women traveling alone would want to be aware of this before hand.
Erick is very responsive and provides ample instructions and recommendations. We connected to the wifi without any problems, although the code is misleading because it is not actually in all CAPS as typed out. In the end, it is a clean apartment, with a comfortable bed, futon, and kitchenette (which I never used, but seemed well stocked). Overall, I would recommend this listing. The location is perfect to seeing all the main sights in Paris, but without being smack in the middle of the tourist areas.
