This hotel was quite difficult to find - no obvious sign on the building, just some portable flags. The staff were not overly helpful, nor was their English very good - it felt like they were Uni students just trying to earn some money, and not necessarily provide good service!
We stayed here with two toddlers in a one bedroom apartment with a cot and a sofa bed. The The sofa bed was extremely uncomfortable for two adults, but our 3 year old was fine on it! The whole room felt very worn, even though the hotel didn't seem very old. The kids loved the brightly coloured apartment doors and the motion-sensor lights in the hallway.
The kitchenette was very small and the crockery/cutlery didn't really seem to be very clean - we washed everything before we used it. (From memory there was no supplied cleaning products, which is unusual in our experience in self-contained apartments.) The bathroom (with a bath!) was quite spacious. We were on the ground floor, and had a glass door out to a terrace with a strange view into the windows of office workers - very strange from our bedroom, and we weren't so sure on the security with this external door from our room. There were coin-operated washing machines on another floor which was really handy - just make sure you read the instructions carefully!
There is a huge shopping centre just down the road with the biggest supermarket I've ever seen in, which was very handy to get supplies to self-cater. There is also a designer outlet next to the shopping centre - shoppers paradise! There is a small park tucked in a corner of the designer outlets, so Dad and kids went there, and Mum went shopping!
Location wise, it is in a very new suburb around an hour into the centre of Paris on the RER trains, and so much cheaper than staying in Paris. There was also secure parking available under the hotel, so we just left our car parked for a couple of days during our stay.
This all sounds very negative, but it wasn't that bad - just a little worn with impersonal service. There seemed to be a few self-catered accomodation places in the area and we'd probably try a different one if we to ever return.
