Marlene is a very nice person and host who was willing to share her suggestions for neighborhoods to visit and local things to do.
Marlene's place is in a very good neighborhood, from which you can walk to a lot of attractions in Paris.
As it is mentioned in the description, the elevator only goes up to the third floor and from there you need to carry your baggage via stairs. You also need to take your baggage up the stairs to the room inside the apartment. It was not an issue for me, but in case your baggage is very heavy or big you may need some help.
