The street is in one of my favorite neighborhood of London.
It's very safe area, and lots of shops and good restaurants near by.
The room is basic, confortable, good size.
The bathroom is ok, the bath/shower works really well.
The flat is not luxurious but what you need for few days in London.
We didn't meet Mark, because he was abroad.
I will definitely go back again next time I'm in London.
