It was a completely great experience. Heidi is been so kind to accept my parents as host, in her lovely and warm house just by the city. The house was really well connected to the city centre, a small and cosy corner perfect to spend few days in london. Although the linguistic gap with the foreign guest, Heidi is been really nice and friendly, perfect welcoming, stay and atmosphere. I would highly recommend to anybody who is traveling to the big city, many thanks again Heidi. :)
