You're tired, and just want to crash before you hit off with Paris, this is definitely a place for you. No stairs (believe me, you'll find this as a welcoming relief!) and it is big enough to fit 2-4 person. I got 2 of my mates to stay in together at Roman's place and it was like a well-equipped apartment; with kitchen equipments and all that you need to feel like home.
Close to the Metro (probably around 5 minutes (or less) to and from Metro station. Roman was kind enough to prepare a list of restaurants around his place.
As it is clean, well stocked with equipments with clean and comfortable sleep and stay, the only point I want to suggest is to highlight the pâtisserie around the place, together with the awesome checklists of awesome restaurants.
Overall, a great stay and a definite must stay for my friends and me!
