Although I didn't have the chance to meet Mina, David was there and was really helpful. He showed me the house and explained everything. They have given a thought on everything; it's renovated, it's in a quiet street, there's tea and herbs available for drinking, hot water available 24/7, a list of tips about the house, the table is FULL of maps and guides about Paris (so no need to buy one) and a TV is ready to give an eye on French channels (or more). The only issue I faced were with my heavy baggage: the street is made of stones so the wheels used to get stuck between the stones and there is no elevator (most buildings don't have) so I needed an extra breath to make it.
To conclude:I highly recommend it to anyone looking for a cozy place, looking forward to be close the subway, local cafés and restaurants and explore the city.
