I stayed in Marco's place for 3.5 months and I absolutely loved it!
It's spacious, clean, well located, and Marco is a very helpful and responsive host.
The Wifi is great, it has a very comfortable bed, lots of space, and is surrounded by bars, bakeries, grocery stores, and anything you'd need for a short or long term stay.
I highly recommend this apartment the next time you're in Paris!
