Don’t usually review, but this was so poor I wanted to warn others. Very very average and amazed to see it claims 4 stars. Bed as uncomfortable as I’ve ever seen. Restaurant poor. Would definitely not stay again.

À very good night sleep clean room amazing breakfast and lovely réceptionnist thank you !

The bed was horrible. They cut the A/C after August, ehich means it's hot in the room. If you open a window, mosquitos race to fly in. There was no table to work from, I used a night stand.

Good

Mercure is a nice place to stay

Enjoyed our stay. Clean. Organised. Car parking overpriced.. 12 euros per day

Room was good size and had option for chromecast on the TV to watch other programs

Excellent hotel, service was very good, staff very helpful. Close to Massy train station and a short taxi ride to Orly Airport.

Near the train station, there is a mall nearby too. Otherwise, the area around the hotel is quiet. Traffic is busy during weekdays.

The only issue I had it was lack of toiletries. I expected there will be something in the bathroom as I was going to Paris only for 2 days businesses trip with small suitcase. But there was only a shower gel which smelled like already out of date.

Ok for a business trip. Nice staff, good breakfast

Good hotel, perfect for business

Very comfortable and efficient hotel. Staff very pleasant and helpful. Railway very short walk so easy to access airport. Very useful having restaurant in hotel, nice meal and good service.

The hotel was very good. Staff were very helpful, room was fine. WiFi was good connection and reasonable speed. The location is good for transport links, both rail and bus services are very good. But not a lot of choice with regard to nearby restaurants. Alcantara, which was a 10 minute walk away, was a very good restaurant.

Nice staff. Bare bones. As one would expect.

Breakfast is the same everyday. WiFi doesn't always work. For one evening I had no WiFi at all, which is bad for business traveler.

overall is good, but no gym or swimming pool is a pitty for a 4 star

Used this hotel as convenient for conference at nearby Ecole Polytechnique. The room was a bit small but pleasant and I think it was probably refurbished recently. Nice shower and good restaurant

I stayed at the Mercure Paris Massy for 4 nights while having business at the nearby Ecole Polytechnique. The Mercure is a perfectly adequate business-trip hotel. It located a few minutes walk from the Massy TGV and Massy-Palaiseau RER stations. The accommodations at the hotel are just fine and the staff is very helpful and friendly. Other than the railway stations, there is nothing of interest in the neighborhood. Other than the hotel restaurant, there is almost no place to eat at night on the Mercure side of the railroad tracks. You need to walk about 10-15 minutes to the other side of the railroad tracks (using a long overpass) to find any place to eat or even a market. The RER B line into central Paris is convenient. The trip will take 20-30 minutes depending on the time of day and whether you get an express(plus the time waiting for the train). I think this Mercure is a bit far from central Paris for being a tourist unless you make the trip only once a day.

The room was clean but, was not insulated well. It was very easy, and unavoidable, to hear the people staying in rooms around you. The heater wasn't adjustable and remained on a high output throughout the night...rather uncomfortable. On the positive side, the reception was very nice and welcoming.
