Maria is a very friendly host, she responded very quickly to all our questions and requests, it is very easy to find Maria's place, and it's so close to all the transport links, it is very easy to get around London living at Maria's place. It's within walking distance to all the trendy East London area. There are full of nice trendy cafes and restaurants around.
The flat is not massively huge as said by other comments, however, I just want to say the bedroom itself is very spacious, it's a double bed and plenty of storage space, plus, the heater works very well, it's always toasty warm in the bedroom.
I would certainly recommend Maria's place to my friends.
