As a couple with a 1-year old boy, we had a lovely stay at Ludovic's place. The apartment is clean, comfortable, and quiet. Our baby slept really well, because the children's rooms are really dark. We loved having breakfast and dinner on the balcony.
Although the apartment is not very close to the typical tourist attractions, we really enjoyed staying in this area. I imagine that normally (i.e. not during COVID) it is easy to get to the more touristic areas by public transport, but we only walked (a lot). There are several supermarkets and bakeries within a 5-10 minute walk from the apartment. There are three parks within walking distance: Jardin du Luxembourg (10 min walk), Jardin des Plantes (15 mins, and it has a zoo) and Parc Montsouris (20 min walk). We also really enjoyed walking in Rue Mouffetard and Les Gobelins.
Overall, we were really happy we stayed in this apartment, and we were sad to go home again :)
