If you're a single traveler then this is your place to stay. It is right next to Champs Elysees and the Eiffel Tower is within walking distance (about 30minutes). You will also find metro stations and various bus stops quite close to the apartment. There are two supermarkets near too.
The room itself is VERY nice, the bed is comfy and there's plenty of space to leave your things. You even have a bathroom in your room! You get a TV and you can even make yourself tea/coffee. In short, in Kathleen's apartment you get absolutely everything you need and even more.
Perfect value for money. I recommend this place 100%.
