It's not so easy to find elevator/escalator in Paris' Metro, so I took 351+T3a from Airport and to Airport because I carried a big luggage with me. Bus is much easier to travel with luggage. Hotel de la Porte Dorée is very close to M8 and T3a, also bus46 to Paris Est Station, very convenient. And there are 2 supermarkets just 1 minutes walking. Room is elegant and comfortable, I wish I could stay longer and visit there once again.
