Sergej is a great host! He was very nice , welcoming and helpful. He gave me really good tips on things to do and see around London.
His house is just FANTASTIC! It is very well located: the biggest shopping center in Europa (Westfield Stratford) and the train station (Stratford International) are just 2 min walk from his flat.

I definitely would come back and I definitely recommend Sergej's flat! Thank you so much Sergej.
