I highly recommend Vincent's place to stay while in Paris. I stayed for a month and I'd come back and stay anytime.
The pull out bed is comfortable and supportive. The kitchen is useful and filled with exactly what you need to make delicious meals at home. As I stayed for a long period of time, this helped keep my costs low as I was able to make myself my own meals. Also there are various shops and markets nearby so getting ingredients is just a few minutes walk away.
The wifi worked well and made it easy to connect for work or streaming. The flat is well sized for one or two people so when inside it doesn't feel cramped, especially with the high ceilings and large windows.
The flat is faces an inner courtyard on the first floor (one floor up from street level) so it's fairly quiet. As a solo female traveler I felt very safe in the flat.
Vincent was attentive and was reachable whenever I needed him. He was a kind host and he'll make anyone's stay comfortable.
