Unfortunately our experience here was not an ideal way to start our London vacation. At first, our experience was positive, as Ben was very hospitable offering a lot of great options for local spots. He even worked with our flight schedule and allowed us to drop off our bags when we first arrived before checking in. But then once we officially checked in is when we noticed some major issues with the appearance of the living room wall. It was then obvious that there was a major leak of some sort but it didn't seem overwhelmingly urgent. But then it rained and there was literally water streaming down the wall near the TV and electrical sockets. As it continued to rain the leak increasingly got worse which then the water was now coming through one of the light fixtures in the ceiling. We were concerned that this was a potential fire and mold hazard which we brought to Ben's attention. He had not responded after some time, so we decided to pack our things and book a hotel room and contact AirBnb. After arriving at our new and expensive hotel, Ben politely apologized and noted that he had previously known about that leak and thought it was resolved. He then stated that he would reimburse us for the first night only and that we should be okay the rest of our stay since it should be "dry" the rest of the week. At this point we had already contacted AirBnb for a full refund which was granted since they deemed the apartment unsafe due to the pictures and videos that we provided. This obviously put a damper on my sister's first trip to London both literally and figuratively since it was not easy to find an affordable place to stay with such short notice. I would just be careful before booking a stay at this location until the leak is properly resolved.
