Our family of 3 - 2 adults and a 13 year old son - stayed at Ogla's 2 rooms apartment for 6 days. Olga was there to received us when we checked in, so she was able to walk through everything with us. Communication was perfect from the point we booked her apartment and during our stay, she occupied the other apartment up-stair, so things were very convenient - not that we need anything as everything was well prepared for our stay. Location is great - a quiet neighborhood not to far from London city center, very well connected by buses and trains. There are nice little restaurants, cafes, patisserie all within walking distance of the apartment, and local groceries stores that open from 7am - 11pm everyday. Overall, I recommend Olga's apartment as a base for your visit to London.
