Lovely 4 Bed House w Garden, 1 Stop to Waterloo

My friends and I booked two nights for a weekend in February. I arrived with two other women and we were told we'd been upgraded to a private room just for the three of us. At check-in, we asked if the other women we'd originally booked with could join us in the room. Reception said they weren't completely sure, but didn't see why not. The hostel manager, an older white man, greeted us when we arrived. The first night was fine. The next morning, we were delayed from using the showers because two guests spent a long time in one of them "having some fun." You could hear them from nearby rooms and bathrooms. We tried to put it behind us and get on with the day. That evening we came back before going out and had no more than seven people in our room, just chatting, not partying. The older male manager barged in without knocking, even though it was an all-female room and two of us had been changing clothes moments before. He yelled at us and said we had to be out by 8 am the next day. We were stunned and felt incredibly uncomfortable. He then waited downstairs and yelled at the other women in their rooms too. Saying he lost his temper is an understatement. We felt unsafe knowing he was staying so close, had keys to every room and could come in whenever he wanted. We left around 1 am and checked into a hotel in a safer area, where we wouldn't be made uncomfortable or have people having sex in the showers. I won't stay here again. I'd advise young women aged 18-25 to avoid this creep. The only thing I saw him wear was tight, flared leggings.
