I’ve stayed in Paris many times for work and vacation, all in the Marais/République, and this place is wildly overpriced for what you get.
Pro's: excellent location, clear and professional communication, comfortable bed, clean, good water pressure and hot water in the shower, air conditioning.
Con's: everything in the apartment is worn and a bit broken, including: a hole in a wall, broken doorknobs, shower doors that don't slide or close properly, a cheap plastic drain cover in shower that flips if you step on it, stains and pilling on furniture, and broken/malfunctioning lamps. Also, there is zero atmosphere and the whole building feels like it’s just all Airbnb’s. This host has some 25 listings so this is a business, not a home.
We had to change our plans at the last minute so the pickings were slim and this place was the best we could find; if we were planning to stay more than one night, we would have left.
