The aparthotel was very cosy and welcoming, even though we arrived at night. Parking underneath the hotel was free, secure and well lit with direct lift access up to the rooms, which was handy for moving luggage. Our 3 bedroom apartment was spacious and reasonably clean, however it was very dimly lit (just not enough lights) and the shower cubicle was missing a door panel (presumably broken but not fixed) rendering it unusable. Thankfully there was also a bath with overhead shower that we used instead. We found the apartment quite cool and couldn't work out how to turn the (underfloor?) heating on. The road noise was quite loud, so had we needed a window open it would have been difficult to sleep. Beware the mattresses are rock hard! We found the location good for using the RER A to get into central Paris each day, with Cergy Prefecture only a 15 minute walk away and trains every 20 minutes with tickets €5 adult one way.
