Our stay with Theo and Maxime was really great! We came earlier than check in time, which was no problem! They gave us many cool tips, also about places you wouldn't find on tripadvisor etc. Furthermore they took us to a small concert and we met their friends, who are also very open :) so all in all it felt like sharing a nice apartment with uncomplicated, cool and helpful young people and we would definitely stay there again next time we visit Paris :)
