Julian was an incredibly gracious host with lots of tips for food, navigation, and sites we would have otherwise missed on our family vacation. I can't recommend him enough.
As for his apartment. Wow. It was incredibly clean, comfortable, and very nicely decorated. It was also huge for a European apartment. If you are in Paris, gives it a look. It's next to an incredible park and only a few minutes on the metro from all the sites. It's also on top of a huge market and bakery that has everything you could possibly need.
If we go back to Paris any time soon, we'll definitely try to get this wonderful place.
