Giacomo's place is in a great area, with lively bars and restaurants & Chatelet station within a few minutes walk. A lot of great attractions within a walking distance, and just a few minutes walk from the Seine.
I stayed in the apartment for a month and found the apartment great for a longer stay too: I appreciated the location and all communication went great. There was a small problem when the hot water boiler broke, but it was fixed the next day without any hassle.
Good to consider is that the place is on a lively street, so noise cancelling headphones are good for light sleepers.
