Jonathan's apartment is one of the most wonderful places I've stayed in. It has a fast access to public transportation, metro either bus and there is a supermarket in the street which is open till about midnight.
There are also many cool bars and restaurants located in the street that made the neighborhood so lively. And the apartment itself is very tidy and clean and accommodated by new stuff which provides you with every little thing you might need during your stay from towels to dish washer. To sum up it was a great experience to have such a nice place while during our stay in Paris.
