Viktor's place was absolutely great! Beautiful and large apartment, Netflix, an equipped kitchen and all you'll need. It is a bit far from the city center, but right across the street from the East India DLR which will take you there in 20-30 mins. Unfortunately my friend and I didn't get to meet Viktor as he was on a trip of his own, but he went out of his way to make sure we had everything we needed.
I really recommend this apartment, had a great time here!
