I cannot recommend Nicolas' place enough. Myself and 3 friends stayed there for a week and it was perfect! Nicolas was very quick to respond to messages prior to our arrival and was available via whatsapp throughout our stay. The apartment is just as described. The four of us fit in the apartment comfortably and had plenty of space. The heat worked well and apartment was always warm and cozy when we would come back from walking all day. The location could not be better. It's steps away from the metro, there are tons of shops and restaurants all around. This place is perfect! we loved our time at this flat so much we are already making plans to come back. Sadly we did not get to meet Nicolas in person and his bar downstairs was closed for most of our stay because of the holidays. They opened on our last night in Paris and what a wonderful way to celebrate our last night! Simon the bar manager was fantastic!
