We really enjoyed staying in Hilary's house. It's very colourful, cozy and practical. We enjoyed the spatious light kitchen/dining room with a huge family table, and glass roof and French windows overlooking the patio/garden. Apart from that, the house has a sitting room (with a TV set and piano, which our children loved :) ) and 4 bedrooms, 3 with single beds and 1 converted attick bedroom with a double bed. The only issue was the adjacent attic bathroom with a slanting ceiling, so being 6''2' I had to use the first floor bathrom to have a proper bath.
The Dulwich village area feels very safe and is well connected to the city centre. The North Dulwich train station is a few minutes away - with a train to London Bridge taking only quarter of an hour. Plus you can get to fashionable buzzing places like Brixton or Pecham by bus in 10 minutes or so. On the spot, there are quite a few nice cafes and restaurants and Dulwich Park and Dulwich Picture Gallery are a short walk away. Another plus was Hilary mum, who lives a few houses away and familiarized us with the house and recommended some local landmarks. In general it's a nice, cozy house where we really felt at home.
