I had a great stay in Aviva Studio. The apartment was small, but modern, clean, very confortable and peaceful. The room I stayed had a tiny kitchen well integrated. The staff were nice and helpful. I felt that I was in a typical london borough but at the same time, very close to the city life.
The location was also perfect, close to Hammersmith station and bus stations were everywhere. In King street, very close from the accomodation, you can find everything you need (pubs, restaurants, pharmacy, supermarkets, stores)
Is definitely a great place to be.
