We stayed in this apartment for 3 nights and it was the perfect apartment for 2 of us - located in a lovely side street of the Marais, close enough for us to walk almost everywhere but also conveniently located close to a Metro station!
Remy was very helpful, easy to communicate with and was there for our arrival and helped to carry my bags up the 5 flights of narrow, winding stairs - as others have said, be aware there is no lift but we were quickly able to get used to the stairs!
From the mezzanine floor, you’re able to see the tip of the Eiffel Tower and each evening we enjoyed waiting for its lights to sparkle!
I would highly recommend this apartment or one of Remy’s others for your stay in Paris and would definitely stay here again!
