Location was great. Room was clean and stylish. However the lift was located in a coffee shop, which means the hotel rooms can be accessed by anyone. In fact, someone knocked on our door at midnight claiming that he left a parcel in our room and would like us to open the door. We refused to do so and advised him to contact the hotel reception, but he keep pursuing us to open the door. After a while we heard someone trying to key in the passcode on our only-passcode-locked door. We were so frightened as there weren’t other locks on our door which we can lock the door from inside. We texted the hotel through Airbnb app but didn’t receive any reply. We called the police and the officer said she couldn’t come over as the guy didn’t do anything aggressive that would harm us. She advised us to contact the hotel, so we called the hotel hotline we found on their website, and were told that the staffs at London weren’t contactable at that moment since it was midnight (The hotel has no reception). The women at the customer service line was very professional, nice and helpful, but there wasn’t anything else she could do to help us than confirming that the hotel will change the building’s passcode first thing the next day. We were so afraid that the guy would come back that we couldn’t sleep all night. Hopefully it was just us having bad luck but the hotel’s security clearly need improvement.
