This place is extremely convenient for going to the airport and to travel around Paris. It does require you have a public transit pass, but once you get the right pass, it's a great place to stay. The sink is very small, and it's a bit cramped, so I would not recommend this for more than 2 people, but I think it's very affordable.
Erick is responsive to questions. Having a washer is also great! Do note that there's no dryer, but there are racks available in the apartment for you to hang up your clothes to dry.
Best part: If you forgot your adapter, Erick has some pretty convenient ones for both USB and his plugs all have adapters. So this helped me out tremendously. Would stay again if I were in Paris.
