If you're looking for a place in Paris, this is IT. Muriel's place is beautifully furnished, well equipped, super comfortable, the view is gorgeous, and I was very pleasantly surprised when I got there as it is bigger than it looks in the photos!
Everything works perfectly: internet, heating, hot water. Also, the bathroom is fabulous! Not only is the water temperature perfect, but there's decent water pressure from the shower.
There are a couple of train stations not far from the flat, there is a pretty good supermarket literally right next to it, and it's not too far from the Marais, which has lots of gay bars and some pretty nice restaurants and shops.
Absolutely recommended, 100%. Will return! :)
