We really enjoyed our time in Paris at Tin and Thuy's property. Spacious enough for 3, especially considering that it is in Paris, I'd easily recommend staying here.
In the neighbourhood, there were slightly more homeless people than you'd find elsewhere in Paris, but there were always a variety of people on the street at all hours and we never felt unsafe.
Easy to reach from the metro, airport, Gare du Nord, etc.
In addition to all of this, Tin and Thuy were friendly hosts who picked us up and dropped us off at the metro, very kind and truly wanted us to enjoy Paris.
Would definitely stay here again.
