In one word: Fantastic!
I am a very picky person and so is my girlfriend. Therefore I am confident to say you won’t find anything wrong with Leas apartment. It has a nice proper bed that easily sleeps two taller people a modern bathroom and a lovely balcony to enjoy your glass of Champaign on. The apartment was very clean, everything you need to cook is in the kitchen and the location is great for going out to dinner, buying groceries or accessing several nearby metro stations.
The communication with Lea was quick and super easy. She organized for us to get the key at the time we wanted and allowed us to check-out so it best fitted our arrangements. We will defiantly stay here again when we return to Paris in the future.
