I really enjoyed my time at Michel’s place. The apartment had everything I needed and was in a perfect location for wandering around the Left bank, lots of restaurant choices, a short walk to the Metro, and a 25 minute walk to the Louvre. I didn’t have any issues with noise. I kept the windows tightly shut and had the air conditioning on due to the heat wave, and slept like a baby the whole time. The stairs are steep and narrow, as is to be expected in these historical buildings, but it’s good to be forewarned I think.
