Justin's place is a jem in Marais area. It is very cosy apartment right next to Pompidou center. It is small but bigger than many other places you can find in central Paris - you get everything you need and it is perfectly comfortable for 2 people. It is very easy to reach by metro and quick and easy ride from the airport, as well. I would highly recommend it and will stay there next time we come to Paris for a long weekend.
