We just can recommend this appartment. Enough space for 2 adults with 2 kids. For teenagers is the bed in the childrens room a littele smal. But everything else was perfect.
Especially the area of London, where it is quit and still you find everything around. Restaurants, supermarkers etc.
Our favourite in London, the Portobello road is just 10 minutes by feed away.
We had a great time!
