Senait's unit in Mile End is a completely private space with tons of room. Two legit bedrooms with a a total of 3 beds. It is on 2 levels, with stairs leading down to kitchen and living room, with big balcony at both front and back - nice for the unusually hot weather when we were in London. Extremely clean, with big TV and fridge. I will not hesitate to come back here on my next trip to London. Senait and Tim made extra effort to meet us when we arrived and get us set up. Everything was great.
The Mile End tube station is much closer to the centre of the city than I thought it would be. Its on the Central line of the Underground, getting you into the thick of it in 5 stops. You can also be in Canary Warf in 10 or 15 minutes by bus from a stop a couple minutes from the flat. There was excess space for 3 of us, and the same would easily apply for 4 people.
