First of all very thanks to Philippe, who was very kind with us. He is an excellent host. Thanks for all!
The flat is located in a very good point of the city, 300 meters of the Louvre Museum and near to the most important points of interest of the city, if you stay there you will be very well located. Also there is a minimarket at 200 meters of the flat (Rue Marengo and Rue Saint Honoré) which opens up to 10PM if you want to purchase some fast groceries like fruit, water, to have breakfast at home or other daily things needed.
About the flat it is a little small but very nice and confortable, the bathroom is really small. If it is cold there is heating and all the things needed to stay as a tourists are in the flat.
In conclusion if you are going to be walking arround Paris during all the day and you want to be in a good located place, comfortable and you don't care about having big rooms this is an excellent place to stay.
