Gemma,
You have, what I would consider, a clean and modest apartment in a less than desirable area of the Le Marais area. It's very noisy, it was hot with only one fan, the bathroom is tiny and poorly lit, the ceiling height caused multiply head injuries and there was virtually no place to put away clothing. Two people with 2 weeks of clothing and not a single drawer. No night tables for a water glass. Extremely hard blocks of foam for pillows that left us with sore and stiff necks. Scooters and motorcycles directly under the windows sounds like there is a street running directly through the living room. IF you had priced this apartment for about HALF of the rental rate I paid, I would not take issue. I paid, at $650 per night, for a much better experience than what we received. When you indicate your apartment's value is $650 per night, there are reasonable expectations that a renter has - I will be comfortable. I will sleep well. I will have good amenities. The apartment will likely enhance my experience. When you wake up to all your clothing draped over the banister, water glasses sitting on the floor, stiff neck from poor bedding, etc, it's a disappointing and an unpleasant experience. We paid a large sum of money for a pitiful experience. I take no joy in saying this. I have NEVER left a poor review and I've stayed in Paris at least 6 times now. You need to provide a better experience, or adjust your price to reflect what you are actually providing.
