The Apartment is very charming and cosy! It has everything you need for a short stay in Paris. I was staying alone just for three days. So, I would advise this small mansard for one person or a couple. Only the internetconnection was a problem. Sometimes (when it runs) it was very slowly! Sometimes it even doesn't work. And I had to repeat the login very often, because after a short time it throw me out.
But Viviana is very exerted to help you in any cases! And she was always reachable via sms. We didn't met personal, but everything worked excellent, also handing over the key.
And I liked the area around. There are many restsurants and cafés and a small supermarket opens till 10:30 pm for buying water, juice and fresh fruits. I would stay there again!! Thank you, Viviana!
