The appartment located in the best part of town! There are a handful of nice places to eat within a few steps (BREIZH - best crapes, Marco Polo - good italian food with charming vibe, Les Editeurs - a variety of French and global food of outstanding quality).
Appartment has everything you need. The bed is very comfortable, despite being a pull out bed, the soaking tub is nice after walking all day. There is fridge, stove and all you need for making food (although we did not prepare any meals). The washer/dryer (one unit) is very helpful, I find that having a dryer is not very common in Europe.
Gary was responsive, instructions to the apparment were clear and easy to find. We flu into Charles de Galle, took RER B from the airport to the Saint Michelle/Notre Dame station (direct, no transfers) and it's a short walk to the appartment from there. Overall, our experience was fantastic. Thank you, Gary! we'll be back.
