I can't hardly imagine how much effort Olivier puts into making sure everything is fine during your stay at his apartment. I was welcomed from his friend Faiza perfectly on time, she gave me the keys and from there all was fine. The apartment is right size for a person or couple, and if you don't mind being right in the centre you have all what you need around. I was most of the time out, and I didn't get the chance to use the telescope. Too bad, you have Paris at your feet when in the apartment!
