Marcel's apartment is stunning and in a fabulous location with Eiffel Tower in sight. Be prepared for the six flights of stairs (no lift) to the front door so not good if any mobility issues or lots of baggage. Beautifully maintained building and the apartment itself is fabulous - clean and cleverly designed and definitely the Parisian experience. It is an architect-designed loft conversion with lovely details. If you are very tall be aware of a few restricted head height corners! Four of us spent 3 nights there for a mums and daughters weekend, so needed to use one of the sofa beds in the sitting room. The kitchen was well stocked though we weren't using it for cooking - too many lovely restaurants nearby. It's a fabulous area of Paris, within easy reach of shops and eateries. There is a corner shop a few doors along the street for any basics, and many local cafes and wine bars.
Marcel was very friendly and willing to offer flexibility if possible. Would definitely go back!
