We, my partner and our baby girl, stayed at the place for 10 days. The apartement is very good for a stay with a baby. It is on the ground floor and a stroller fits easily in the entrance hall. The bed is big enough for 2,5 people and there is also enough room for an extra bed for a baby (you have to bring the baby bed on your own).
The apartement was like in the pictures and like described. The apartment ist very clean and there were more than enough extra sheets and towels.
The owner also gave us a lot of nespresso capsules for the nespresso machine in the apartement and there was also tea and soap. The owner was always there for us via whatsapp and replied very fast.
As the apartement is on the ground floor we advice you to bring some warm clothes for the evenings as it can get cold even in summer. At least you wont suffer from heat even if its a hot summer in paris.
The neighborhood is very charming, lively, with a lot of bistros, restaurants, bars and also a lot of tourists. Its very nice to stay in that area. The sleeping room of the apartement is next to a little courtyard. It is very calm.
