Oliver's son helped us check in on the first day. I did not meet Oliver during our 3 night stay at his place. On the third day (before the last day of our stay), I received messages from Oliver asking why we did not check out yet as we're supposed to do so by noon, so he could have his another renter coming later that day. Even though later he acknowledged that it was his mistake, i felt uncomfortable for the rest of my stay.
Minus another star is due to cleanliness. As mentioned in other reviews, the place is dusty. I only used the bed and one desk next to the bed since i did not want to touch other things. I even had to wipe the desk before using it. My allergy acted up at night (sneezing and itchy throat) probably due to the dust. The room is spacious and in a new apartment (compared to others in Paris), so it makes up for it.
Besides those 2 things above, the place is near the metro station, about 3 blocks away. Decent for its price.
