Guillaume's flat is amazing. I stayed with my family (we were 5 adults) and were very confortable. Tha place is very stylish and looks just like the pictures. Location is really good (Line 7 metro station a block away; Gare de l'Est and Gare du Nord also very close) so you have easy access to everywhere in Paris (including the airports). The area is also nice and quiet, with a variety of shops at walking distance (boulangeries, restaurants and supermarkets). He was very kind during all contacts and wellcomed us with a nice bottle of wine. We had a great stay and for sure we will choose it again in future trips to Paris.
