I stayed in Jussieu for a month while working and studying in Paris. The apartment is very well situated in the city being served by two metro lines and a number of busses, which made commuting around very easy.
The nearby Jardin des Plantes is a very beautiful garden and I enjoyed passing time there during the hot afternoons of summer. The quarter is lively with many nice cafés, bars and restaurants. Despite being next to a major university, the apartment is very peaceful as it looks out onto a quiet side street with the bedroom on the side of the inner courtyard.
In general, the apartment is in very good condition and is well equipped. The kitchen has a nice induction burner, which made cooking a pleasure.
Filippo was a very good host to me - we didn't have any issues in communication and he helped even arrange me a plumber very quickly when the toilet mechanism had a minor issue.
All in all, I would definitely recommend the apartment for anyone wanting to stay in the centre of Paris!
