I stayed for a month and the whole experience was incredible. The apartment was exactly what we expected and even more.
Flora is always available and replies very quickly to any question or doubt.
The neighborhood is very very interesting, close to Montmartre and to the trendy Rue des Martyrs: bars, restaurants, markets of all types.
I studied French close to Notredame and in less than 20 minutes I was there using the metro. But I recommend also using the bus nº 85, since it passes right around the corner.
All the equipment in the apartment functioned just perfectly. Never a problem.
To sum up: highly recommended
