We stayed for 9 days, very peaceful nights. We always left in the morning and came back late and was able to have good night sleep as it was very quiet neighborhood.
Flat was as described, clean, bright, spacious, great for family with small kids. Bathroom was spacious for Paris standards too.
Though we didn’t need heater as days were quite warm, nice warm close to hot flat welcomed us ! ( i had to ask how to turn off the heater even)
Easy access to three different metro lines. On good weather days you could easily walk places around Opera.
Overall was great stay !
