I and my family (husband and 2 kids - 12 and 6 years old) spend 6 days in Sofia' appartment in the end of March. We didn't meet Sofia and didn't in touch her during our stay in Paris but she sent us very detailed instructions how to find appartment and gave very useful tips for staying in Paris and feeling comfortable in her appartment. The appartment itself is very clean, exactly the same as on photos, fully equiped (we used not all). Location is funtastic. We found nice bakery, supermarket, good cafes and restaurants around. Metro is near (~100 m). Appartment is in safe and in quiet district and it's very comfortable after noisy day in Paris. I can only mention that appartment is too small for 2 adults and 2 big kids (we couldn't find space to store our staff for 4 persons).
Overall we would like to thank Sofia for our good stay in her nice appartment. I definitely can recommend it.
