The apartment is close to both Notre-Dame de Paris and the Sorbonne University. It is also close to the metro lines 4 and 10 which connect you to virtually everywhere in Paris. The neighbourhood is very nice and offers lots of facilities (cafés, supermarkets, restaurants, bakeries and the Maubert market).
Appartement dans le 5e arrondissement, proche du métro lignes 10 et 4, proche RER C. Sympa et cosy, boulangeries, cafés, supermarchés, laverie à proximité immédiate.
There are no rules, apart from being clean and respectful ;)
I do remind you that the apartment is unfortunately not suitable for children under 12, for safety reasons.
