Sebastian is an excellent host that is really attentive to communications. The accommodation is clean, spacious, full of amenities (including a robe), and in an ideal location just beside the Old Town station. The flat is on the ground level of the building, and due to its location near the tube station, you can hear the trains passing by, but it is otherwise quite peaceful and away from the main street's noises. I would really suggest staying with Sebastian; he is genuinely concerned about his visitors and would go out of his way to make you feel at home.
