For anyone thinking of staying here, its not as bad as the previous comments suggest (since they were a long time ago and the hotel has improved). Basically you get what you pay for. It is a budget hotel near to plenty of resturants (some of which are novelty) and an extremly regular bus service to the stations or paris. The rooms are not huge but if your there for sight seeing and just need it as a place to stay my partner and i highly recommend it. Many of the staff we met spoke English and were all more than happy to help us out. The beds were very comfotable - ours had a memory foam matress!
Not many electrical sockets.
all i suggest for you to do is bring own towels (as not very big) and also bring haridryer etc.
Breakfast was a fair price for an all you can eat buffet with authentic french food.

Awful experience. I payed 48 euros, would not go there again even for 10 euros: matress was really loud, room was not really clean, bed sheets had two big holes (about 2cm diameter), WC anything but inviting, anyone can just walk around the prking lot, dy and night (in the middle of an industrial area, it would be nice having a fence, at least)... I usually sleep at Etap (sometimes are not really clean either). I tried Stars once, never again, if I don't get anything else, I rather sleep in the car, nd spend 40 euros on Petrol while having the engine/heating on during all night!

I finally reached the hotel late at night in early January. The last three letters in "Hotel" were burned out, and I could not see another person anywhere near this industrial area.
-My bed was a padded mat similiar to what some people use when camping.
-I wish I had been camping because I think that it would have been just as comfortable. I say that after 10 years in Boy Scouts and 20 years of camping, hunting, hiking, and fishing.
-The hotel was robbed my 4th night there. Luckily the police didn't try to question me very much since I speak only a handful of french.
-My family called me many times, but the staff never gave me a single message. I discovered that my family had been calling from a fellow traveller from Alabama or somewhere down south. He took a message from my family member, and gave it to the desk attendant to give to me. Of course he did not repeatedly.
-Late at night the desk staff must of had many good times. I could hear all there conversations, except when a 747 or many larger jets were leaving the Orly Airport.
-Orly Airport is extremely close, but to get there affordably.(bus, train, metro) It will take you much longer.
-If you can find the bus which takes you to the train station you have a great start. Just make sure your on the correct side of the street. The train will then take about 30 minutes to your stop, and then you'll need to take another bus.
-Hopefully while your on the train you will not be robbed by the gypsy children.
-I saved alot of money by not knowing that I hadn't bought the correct rail pass for my area. The metro maids attempted to fine me, but luckily let me off. Some U.S. credit cards do not work on certain Euro credit card machines.
-Also I was lucky the Metro maids where nice, and understood that I had no idea what was going on.
-I took a taxi. Most money I have ever spent to sit in a car. $50+

-The bus service ended about midnight or 1 AM. So when figuring in at least an hour of train travel from Paris to the near train station to grab the bus. I had to get out of the city by 11:00. Which can be difficult in a nighttime city were everything happens later and is only open at a certain time.
-I was there for 2 weekends. Both weekends the police had to come breakup fights. The discotecque party goers migrated to the hotel parking lot.
-The hotel staff walked in on me multiple times in the morning. Even though I was usually headed in to the city by 8 AM.
-A chair against the door helps combat cleaning staff from barging in since there are no inside door locks.

In closing I hated this place. My advice is to NOT stay at the Hotel Stars in Chilly Mazarin. Pay the extra money for a place IN Paris preferable near a metro. The metro system is easy once you get a map, and affordable. I lost days of time in Paris because I bought the cheapest room in an industrial no man's land.
-Save yourself and your vacation from this hotel.
-The staff does not speak English well enough to communicate.

Myself and my boyfriend stayed at this hotel the weekend of 28th Sept!!! We booked this as a package deal for a cheap break to Paris to watch the Rugby, and by god if we hadn't had the rugby to watch I would have been completely devastated!!!!

Upon arrival, it was notably obvious that you are literally in the middle of an industrial estate with 2 large night clubs directly next door and a petrol station about 5 steps from the front door....

Inside, all seemed well, reception were friendly, our room was directly at the top of the stairs, every thing seemed clean and we noted the nautical theme (very amusing).

Upon entering our room which was extremely small, we found that not only were we paying to sleep on a metal camp bed, but the shower room was a contained wet-room unit with a door that did not shut with the tiniest towels ever, that not even a 4 year old could benefit from!!!!

The shower head was attached to the top of the wall, so unless you are over 7 foot tall you were just showering the rest of the room, literally as you could not shut the door!!!!!

To get to Paris was a nightmare, the trains come literally once an hour, although their saving grace was that they play music at the stations which was quite novel.... On Saturday it took us over 2 and half hours to get to Paris!

When we returned after a 20 hour day, completely exhausted, we were greeted by a noisy karaoke bar to the right of the hotel, 2 night clubs to the left and to our delight, our bedroom window was above a coach parking bay, and directly under a flight path!!

Least to say it was the worst nights sleep I have ever ever ever had in a hotel, with constant people screaming and shouting when leaving the club, cars pulling in and out with stereos blasting, planes flying over, door slamming - all whilst on the most uncomfortable camp bed!!!!

On our last night, we spoke to reception - asked for a wake up call at 5.30am and a taxi for 5.45am. The following morning we got ourselves up (without the promised and advertised morning wake up calls), and upon walking down were told our taxi was waiting, brilliant we thought - but we were not told it had been waiting since 5.30 and the fare was already nearly €20.

The service was crap to put it bluntly and I wouldn't even send my worst emeny there! As I stated before, if it wasn't for the lure of the rugby game and seeing some of the tourist side of Paris I would never recommend Paris to anyone!
