This flat is located in the best place to enjoy the Marais and Paris and I highly recommend it.
Really everything is in walking distance, including cafes, great restaurants, museums, parks, metro, supermarkets, amazing bakeries, and even the Seine River.
The Marais of course is one of the prettiest neighborhoods of Paris and it is entirely around the flat. The Picasso Museum is literally down the street from the flat.
The flat itself is beautifully designed and includes everything that you'll need for your stay -refrigerator, oven, micro, stove, kettle, dishwasher and a washing machine. It also includes all the cutlery, plates and glasses.
The first two days were quite hot, and all the instructions were written in French, so we opened the windows during the nights. But the central heating (radiators) is controlled from the kitchen. There is no air conditioning in the flat.
The main drawback of this flat is the fact that it is on the third floor without any elevator. Before you shrug it off, I have to state that the staircase is extremely steep, and it might be VERY difficult for some people to manage the climb.
The second drawback are the towels - my guess is that they are very old and have been washed and cleaned for years. There current status and feel is more like sandpaper than a soft towel. This is something that needs to be addressed by the owner.
