This may be the best location in Paris! Tuileries Metro stop right across the street. You can get anywhere in Paris easily and quickly from this location. The apartment is easy walking distance to the Opera, the Marais, Les Halles, Place Vendome, Concorde, etc. And when you arrive in the morning, you're only a block away from Angelina's -- the best breakfast spot in the city.
As for the apartment itself, it's extremely well equipped. Modern bathrooms with excellent showers and -- what a treat -- towel heaters! Good kitchen with large fridge and a dishwasher. We shopped at one of the local markets and we were certainly able to cook a fine meal! (We didn't use the clothes wahser and dryer, but they would be handy if needed.)
Jay -- the host -- is extremely helpful, with plenty of good tips, local knowledge, etc. He made the entre process simple and friendly. We were two couple, and all four of us would absolutely book this apartment again.
