I was able to check in around 11am and Paul welcomed me to the apartment and showed me around--he even carried my 23kg/50lb luggage up the stairs which I still feel equally grateful and horrified about. It was very easy to communicate with Paul; before my arrival, Paul kept me up-to-date with information with helpful information that I needed to know, If i had any questions, Paul responded within a couple of minutes. The apartment was very clean and had everything that you needed and is very close to a grocery store and the metro is across the street. The apartment is located in a courtyard off of the main street but you don't hear the street noise in the apartment. I highly recommend staying at Paul's apartment, for your stay in Paris.
