Marlene's house was amazing. Space of the whole house was big enough for my family (7 adults). Bathrooms and toilets were separated which was good for a big group stay. Toilet was tiny and located just next to stairs so must be careful while using it. Be aware that stairs are quite narrow. However, elderly in my family can stay comfortably.
Location is superb, quiet road, near a supermarket and many bakery shops, restaurants. It is 5 minutes walk to train, metro, RER stations.
Highly recommend!!!
