View as said already by everyone else is spectacular and well worth the stay. There are so many other great things worth mentioning though. We actually loved the neighbourhood with its many great Vietnamese and Asian places to eat and many shops within a minutes walk! It's also got a great transport connections with a metro station 2 min walk from the flat!
The bike cards and phones were an amazing added bonus to have! We found discovering Paris on a bike an excellent way to do it and it's so easy to get around and find stations! We would probably not have done it though if we didn't have the cards from Olivier so a great thank you for that!
He has been a great host letting us check in early and go later and truly has thought of everything that you may need.
We are already planing our second visit to paris and we would def like to stay at the flat again:).
