I have been hosted by Tanvir for 3 nights with my two friends.
The place was good for 3 people.
The house is really closed to the city center, you can take the underground at whitechapel and then go everywhere.
You can also go to the tower bridge by foot (it takes like 20 minutes).
The host was nice with us even if we were 2 hours late.
Everything in the house is like described and pictured in Airbnb by Tanvir.
We really recommend this house.
