The Quentin's flat is absolutely terrific (wonderful, excellent). It is tastefully furnished and it is really very functional.

The flat was very clean and equipped with everything you may need. It consists of two floors and the boys' room can accommodate 3 children. This room was the favorite of my three children who "had a blast" with the toys provided.

The flat is exactly how described on Airbnb and the experience was similar to what you can do in a boutique hotel.

The neighborhood - north of Notting Hill - is very nice and quiet; it is very easy to travel by bus (56, 6 to reach Victoria Station 30', Buckingam Palace 20' or Oxford Street), underground (Kensal Green station) and overground (Kensal Rise station). For example, those who plan to visit the studios of Harry Potter: from Kensal Green station you can get there directly in about 30 minutes.

Quentin greeted us on arrival, and despite our delay, he introduced us slowly throughout the house the whole house.

I'm sure it is a perfect place where a family with children can stay.
If I return to London I would not doubt in choosing the apartment Quentin.
