We chose Sophia's flat because we wanted to stay exactly in the area where it is located and in this regard it worked perfectly - you can easily reach on foot or by bus many interesting places, restaurants, bars and nightlife (Broadway Market, London Fields, Hackney and Shoreditch). The Overground station is literally one stone's throw away from the apartment (you can see the platform from the windows) and Bethnal Green Underground station is less than 10 mins away on foot. You also have many buses just outside the door.
The building is so new you cannot even find it on Google Earth! Meaning the flat is brand new, extremely clean, spacious, bright and very comfortable. There's everything you may need for your stay with brand new equipment. Only two small remarks: very little - or none- storage place (the hosts live there so drawers and cabinets are full of their stuff) and, if you want to eat in, you will find plenty of glasses but some basic pots are missing and you'll have to share the one and only tea spoon :)
We didn't meet Sophia since she was on holiday herself but she was always available and responded to every request we made.
We have really enjoyed our stay in this flat and would definitely recommend it!
