A two weeks car tour of Normandy, maybe Le Havre is a bit far from MtStMichel but you can see all the rest enjoying it. Normandy is worth the visit for food and relax, and for visiting different places; people are nice, too.
About the hotel.
The hotel staff was young, kind, expecially the reception, breakfast, servicing and night guys.
I had no problem, just a couple of details of organisation: the hotel is all new, too new, meaning they have no spare furniture, so we kept our big luggage on the floor: it seems tuned for 3-4 days staying.
Also the parking was partially rented to SCNF (the station is quite close, as you can see from some people in the neighbourhoods at night). This means "first come, first served" but also it has to be said there were quite enough places on the streets for cars (cheap: 3Eu half a day, 6Eu full day).
Air conditioning could be better, too warm...but it is a rare situation feeling hot over there.
