We enjoyed our six day stay at June's appartment where my daughter and I shared the bed room. We enjoyed having the breakfast or a light lunch on the balcony. We took advantage of the shops nearby (Marks & Spencer, charity shops, bakeries, cafés) and of the huge Hampstead Heath park. Going downtown is easy and direct with the 24 bus line or with the underground from Belsize park. We'd highly recommend June's place.
