We spend 4 days at the apartment of Julien and Karimas, and we highly recommend it. The apartment is very cosy and clean. Also, everything you need is there: kitchen, washing machine etc. Although we haven’t seen Julien and Karimas, the communication was perfect. They were very helpful and gave us useful advice regarding our stay in Paris. The location was good, since it is withing walking distance of the Sacre Coeur and Montmartre.
