13th district is a bit far from city center, but Paris is basically not big at all and well connected with metro, so Johann's place is ideally located. There are good vietnamese restaurants too so pls have a try if you need warm soup during your trip!
This flat has super sensible interior, and you can see pretty spacious room comparing to other's accomodation in Paris. I'd love to stay here again for my next visit! Strongly recommend! You won't regret!
