Jonathan's place is a very well located house with multiple rooms and a common, bathroom (no window), kitchen and eating area.
The room is as in the picture and it is very spacious. Kitchen is a bit short and old in items and stuff but you can survive properly. The terrace in front of the room lacks a little bit of privacy but it is also very good to get fresh air. Sleeping quality was good and almost no noise around. I would repeat again if going to London, as negative point the bedsheets were not smelling as fresh as a hotel and little more time of open windows would help.
