I think I spent in total (multiple intervals) almost 2 months in David's appartment (le Matelot).
Apartment is located in a quiet building, even though it's extremely close to where most of the action happens is Fecamp.
When I arrived for the first time, I was greeted by David (the owner). He showed me the place and explained me everything around (how to use heating, laundry etc.). When I left we didn't meet anymore (we agreed in advance where to leave the keys). Same when I arrived second time. Communication was excellent every time. Everytime a good, local, cider was waiting me in the fridge :)
You can always ask David for tips regarding activities, locations, events etc. He gave me several ones.
If you're the type of person who likes to cook, you're lucky: kitchen is fully equipped with absolutely everything you need.
If you're the type of person who like to go out and eat, you're also lucky: most high rated restaurant in Fecamp are maximum 5-10 minutes walking distance from apartment. In another 15-20 minutes walking you're in the city center.
Beach is indeed 50 meters away from the apartment. The apartment is literally on the first parallel street near the one close to the beach.
Port is also around 5 minutes walking distance.
There are lots of free parking spots around. I usually parked in the front of the building. When that parking was full, I parked on the street near to beach (<5 min walking). I always found available spots there.
I forgot to mention about the cleaning of the place, which was exemplary!
I highly recommend this place. Description provided by owner is 100% accurate.
