1)No noise from underground, huge plus
2)Very clean bathroom/toilets, huge plus
3)Easy arrival/departure with electronic code to frontdoor+ room, huge plus
4)For me it was a perfect location, huge plus
5)Only minor negative, which I assume is typical in London, is that bathroom flors are pretty cold, remember to bring slippers ;-)
6)I can only recommend to book this apartment. Thank you Omar for renting this out.
