We really enjoyed our stay at Mariusz's flat. It was easy to find as Mariusz was waiting outside for us so that we could see which building it was. I could tell he had to rush over then rush back to where he came from, but he still took the time to explain everything we needed to know and answered all our questions. He was the perfect host with local tips and guidebooks in the flat. The flat was cosy, well maintained and had all the comforts of home (including coffee machine!). The location was great and it was surprisingly quiet inside considering its proximity to London bridge train station. You barely hear the trains at all and the street the flat is on is also very quiet. I felt safe in the area even though it is a quiet street in an urban area.
