Unfortunately I was not in a position to receive e-mails during my stay in London, so it came as a surprise when two young women entered the apartment not long after I had arrived. They introduced themselves and seemed pleasant enough and I only saw them again in the evening when I got back to the apartment. What was a bigger surprise on the second evening after I had put the chain on the front door and gone to bed, I heard someone trying to enter the front door, I shot out of bed and asked who they were (a man and a women). The lady explained that they had booked to stay there the night and they were also unaware that anyone else had use of the apartment. I felt I had no choice but to let them in and felt very vulnerable in my night clothes. She then said that they were going out again and would try to be quiet. Well they arrived back at 1:45am and talked for half an hour nonstop. Needless to say I had a sleepless night and felt uncomfortable. If I had known other people were staying there I would not have booked this room and of course will not be staying there again. Not recommended for lone women travellers.
