Wonderful place and great hosts! They speak english what make the communication very easy. At first I didn't want to book because the flat had no ratings, but I took the risk and it was wonderful.
Very well located, you can walk to everywhere, especially the Louvre, Luxembourg Park, Botanic Garden and easily explore arrondissements 1 to 6 walking.
The flat has good lighting and it is very cozy. It has everything you need for a short or long stay (even washing machine). We stayed 1 month.
The sofa bed is incredibly comfortable and with a good bed linen. Good shower too.
At night can have some noise in the street, but that didn't bother us. Also there is an elevator. Enjoy your stay! We definitely want to come back. Thank you Charles!
