Branko was very welcoming, we would rate it a 5! In our specific case we had a late flight into CDG and he accommodated our 1AM arrival and our 7AM departure 2 days later. He took the time to explain all the features of the apartment, where everything was located and how to use the appliances. He was also very responsive over e-mail and text once we were withing two weeks of the booking. His description I'd rate as a 4, really accurate. To start with the need to be aware of, the place is located at the top 5 flights of narrow steps down a street not wide enough for a car. Also there is a restaurant attached to the building so you have to deal with their trash, food smell and customers. However, if you have ever been to Paris you know this is part of the Parisian atmosphere and does not reflect negatively against the accommodations. This small studio has all conveniences of an apartment minus a clothes dryer and a fan. The shower was big enough for a 235lb (110kilo) male, the kitchen was very functional with a refrigerator, microwave, plenty of tupperware, dishes and pots. The sink is very functional for cooking or cleaning up and he has many hidden storage compartments in the area. He has an iron and a full size ironing board! The bed is not perfect, but there is no minus points as most hotel beds are not the greatest. This studio is really very modern and clean, all pluses!
The neighborhood is a 5, Best neighborhood ever! The location is easy to get to from RER B train station from CDG. Literally a 6 minute walk from the closest train stop. The location is next to all your typical Paris landmarks and museums and plenty of restaurants, bars and clubs. Whatever you are interested in, you will find! Also it is close to souvenir shops with inexpensive trinkets for your family. You will definitely enjoy your stay here whether for work or pleasure. The apartment is small, so I would not try more than 2 people, unless the third is a small child. Great for couples that want to live the Paris lifestyle and save money on going out to eat by using the kitchen to prepare food.
