If everything is location, location, location, ... Zazie’s is perfect ... walking distance to a lot and great Metro stations to go all over.
Lovely market at blvd Raspail 3 times a week, shopping and cafes all around and the best Bon Marche just around the corner for whatever you might fancy.
The other great thing is that it is on the ground floor ... so no stairs to climb at the end of a tiring day.
The cons are ... if you are sensitive to noises ... no traffic but you hear everybody that comes through the main door, and of course the walking of everybody in the apt. above.
The bathroom is extremely small ... good shower ... that’sall.
A few other features could be easily improved as towels, sitting pieces and lighting !
But I spent two wonderful weeks there ... of course .. with the best of parisian weather so I was outside most of the time.
