Pascal's aparment is fantastic. Location cannot be better, clean, quiet and has a small kitchen (with a coffee machine!): just perfect for a couple to spend a week in Paris.
We arrived after midnight and were able to get in with the instructions Pascal left for us without him having to wait for us to provide us with a key. This was even more convenient since our flight got delayed and we didn't have to worry about commuincating it to him because we knew he wasn't waiting for us. He stopped by on the next day to make sure we have everything we need and to provide useful tips on the surroundings. He was easy to reach by email through the week and helped us pre-order a taxi back to the airport when we needed it.

This is a studio apartment (only 1 room + bathroom) and it's located in the 4th floor with no elevator so if you need more privacy than that, or if you can't climb stairs easily, then this place is probably not a perffect fit for you - completely your loss.
