Marie's appt is beautiful. Its on the 1st floor and is served by a lift. Whilst this area around the Gare du Nord is sadly dirty and quite noisy, once you are inside you are a world away. Everything has been thought of in terms of all basic amenities and the appt was spotless. Mero and RER are a short 5 - 10 min walk away so it is well located from that perspective. Marie was a super host - she replied to any question almost immediately and it was great to meet her at our check out.
