We stayed at Dominic's apartment for 5 days, we're a family of 4 and the house was perfect for us.
It's really easy to get to the center of London, the Stratford High Street station (DLR line) is about 5 min from the apartment, and the Stratford Station (Central and Jubilee lines) is 10 min away.
All the equipment in the apartment works very well and Dominic was always available for any questions we had.
The only thing to point out is maybe the cleanliness of the dishes in the kitchen, but nothing major.
We would definitely stay in Dominic's apartment again!
