Eric's apartment was charming: a perfect mix of classic Parisian architectural detail and a modern kitchen and bathroom. Most importantly for us, it was baby-friendly, with a portable crib and high chair. We did have one flight of stairs to navigate with the stroller, but it was manageable. Street noise was substantial when the windows were open (a necessity in the summer without AC), so we moved the baby's crib into the bedroom. Light-blocking window blinds were very useful, though, and worked well.
The location was great--nice neighborhood, with lots of grocery stores and restaurants within easy waking distance, and very convenient to metro (Voltaire) and bus stops. Eric was a welcoming, responsive, and considerate host, helping us with our bags when we arrived and walking us to the taxi stand when we left. We enjoyed our stay and would certainly stay there again. Highly recommended!
