I didn't meet Ethan because he was away on holiday but communication was easy and replies were quick. Met his friend at the DLR station close by to collect keys. He was very accommodating with the check in/out times. The apartment is in a convenient location - literally 2 minute walk from DLR station (if that) and very close to a local Tesco and Co-op for groceries. Also the apartment block has a secure entry phone system so you feel very safe (especially if you're a lone female traveller like myself).
