Very nice communication, clear instructions, very easy.
the only issue is that this is in the basement, so you don't have a window to open, but there is an air condicioner. good for shorter stays.
the location could be better tho - it was in the Pakistani/etc neighboroughood, so me as a white girl wouldn't go around there in the late evening on my own, but it's just me. didn't have any issues when i was walking with someone.
in the same time location is great for London Tower Bridge (which is just 1 stop away).
all and all i'd recommend.
