We did not meet Vivek but he was great in providing all details and answering questions promptly.
The flat is very nice and bright, comfortable. We spent one week and really felt home. The neighborhood was just perfect: stores, market, tube station on the northern line was ultra convenient.
Only two downsides: the noise from the busy street in the living room was very loud, but the bedroom is really quiet. And the fact that there's few cutlery and kitchen utensils if you want to cook a bit.
Great place to visit the city!
