I stayed at Elias and Sandra's' place for a little over a week. They are amazing hosts, very friendly and welcoming. They make you feel at home. The building is very safe, the apartment is fantastic and the room has everything you need. The city center is around 20 to 30 mins by DLR+underground, quite an easy commute. Very close to Canary Wharf and some shops around for your day to day needs. If you are visiting London I would definitely recommend you staying here. My best Airbnb experience so far and I think a hard to beat.
