This place is really a rare gem. Isabelle was very welcoming and accomodating. She made sure I was ok and everything was going smoothly. In the appartment hang pictures of people that have been in this appartment and flags of where they come from, you'll see that Isabelle's family is very open and curious about dfferent people and cultures. The neighborhood is really nice, very lively. The appartment is conveniently located, easy acces from both airports. The Catacombes experience is a MUST, after you come out of your visit, you'll see your studio differently. Luxembourg park is near, if you like walking. Many important avenues are near buy. Lot's of restaurants, stores and coffee places near by.
The only thing that can be a downside, if you trully are a light sleeper, is the train tracks that is really a few metters from the building, which is why Isabelle always makes the point before accepting any guest. For all heavy sleepers and regular sleepers, just bring your earplugs and you'll be fine.
Don't miss this place, it's a good one!
