Serena is an amazing host! She was very accommodating even when I came for New Years. She sent me specific directions of how to get to her place and it was very easy. She is a very nice person and easy to talk to. Her place is also a great central location right next to a tesco shop, the metro and a short walk to the city center, it is also a very safe place to walk back and forth from the city center. I would strongly suggest staying here to anyone who was going to London
