Diana was a really kind and lovely host! The check-in was without any problems at 11 pm. We've only been there for 2 nights , but I would definitely come back! Every night she made us tea , talked about our plans and looked up the best way to come around. The room was really clean , the bed comfortable and you could see "the shard" from the window . You can hear some cars from the room, but that didn't bother us at all. We could also send her SMS when we were not at home. We asked her for recommendations to eat dinner and she answered really fast with good tips! The description to reach the house was good to understand and you can reach the city center very easily with the transportation system.
We would really recommend Diana's flat! :-)
