The apartment is beautiful and super clean and comfortable. We had 2 adults and 2 teen boys and there was space to spread out. The location is nice and safe and quiet, a few blocks away from bakeries, grocery stores, restaurants. We tried several of the bakeries and really enjoyed the eclairs at L. Pinzani on Rue du Rocher. Several Metro stations-Europe, Rome, and Villiers are close. Gare Paris Saint-Lazare (train and metro station) is about a 10 minute walk.
It has a small washing machine, but no dryer; we used a drying rack on balcony. The apartment does not have air conditioning, but there are several Dyson fans for the bedrooms and it cooled off overnight for us - we could leave the windows open at night. There is not free parking. Jeremy helped us figure out how to park.
