Zhang apartment is within walking distance from the Eiffel Tower. There are restaurants, a wine store, supermarket and a boulangerie very nearby. The metro is also very close.
The apartment was very clean and had all necessary amenities. It was very warm, no need to turn on the heater.
The toilet is inside a cupboard which is very small and you can't really close the door. We already knew that before making the reservation, so we didn't mind.
The apartment is in a building of studios and there is a long corridor with loads of doors on each side.
The area was safe. We did see some rough sleepers at the metro exit, but they didn't give us any trouble. There are usually loads of people in the street and having drinks at the nearby pubs.
Zhang was helpful and available when we had enquiries.
