We wanna get in touch with the local people. Nothing better than staying in their home. Thank you airbnb to be the bridge between us. We found a home in Stratford. It is very convenient but the price is similar to the nearby hostel or hotel. Good deal. Location-wise, it is walking distance to train station and olympic stadium. Restaurants are around the corner. We are in process in communicating with the host. They are pretty nice and welcoming. Waiting for their confirmation then our London stop is settled!!
