I stayed at AJ & Olia's place for 8 days. The location is fantastic and beautiful, extremely central and close to several tube stations and buses. Although it's very central, the street the flat is on is very quiet. The flat itself is also mostly quiet, though you can hear the neighbors moving around quite clearly when you're in the bedroom (which is located in the basement). It was loud enough that I was initially alarmed that someone might be in the flat when I woke up the first morning. The flat is comfortable, but smells a bit like cigarette smoke, particularly in the living room. I didn't meet AJ or Olia, though Olia did insist on coming to the flat to pick up an air mattress during my stay. I had plans when she initially asked to come, so I asked her to come earlier. Shortly after she was supposed to have arrived, she texted to say she was stuck in traffic and would come while I wasn't there. When I returned later, she had left many lights on throughout the flat, despite saying she only needed access to a closet in the kitchen. This was mostly innocuous, but I thought it was a bit strange and it did make me a bit uncomfortable, especially because it may have been unsettling for my dog who remained in the flat while I was gone. Beyond that, I had a lovely stay and was on the whole pleased! Thank you AJ and Olia!
