Sofia's place is great, it is always clean and near to the metro, also is near to La Bastille and a street called Rue Rivoli where you can walk all the way to much of the tourist places. Since the beginning she was super nice, she gave clear instructions and she was super helpful. Also she provides you with tips of the city and city maps and tells you how you can move or whatever you ask, she always tries to help. I recommend this place 100%, you'll have a great time.
