We had a great stay in Anna's cute studio, located in the 16th arrondissement.
It was exactly what we wanted: a safe, clean apartment in a nice and quiet neighborhood, not too far from the center, but still a little on the oustide so we could sleep in. Anna was really sweet and helpful, we got in so late but she made sure we would have everything we needed.
She was worried the apartment would be too small for two people, but honestly it was fine for us.
