This studio is fantastic. It's literally two minutes from one of the main train stations in Paris which makes everything the city has to offer within a 10-15 ride.
Patrick and Franck are also the best hosts I have ever had with airbnb. They are incredibly attentive and make the check-in process really effortless and easy. They checked in on us halfway through our trip to see how things were going and if we needed anything else.
The only drawbacks are climbing up the five flights of stairs every day and that it wasn't right in the thick of the action. But like I said nothing is far and the value of this studio far outweighs any cons. Would recommend to anyone traveling to Paris. Especially those coming from Europe as the station is one of the main ones servicing the Eurostar and other longer length train rides.
