Quite simply: Zoe's flat in Chiswick is fantastic.
We stayed for a wonderful month with our two young children. It was a terrific home away from home, with tons of amenities within a short walk in any direction.
The high street (<5 minute walk) is packed with supermarkets (massive Sainsbury's, smaller Waitrose, and M&S Food Hall), restaurants, coffee shops, and stores. Two tube stations (Chiswick Park; Turnham Green) are within a 5-10 minute walk and are both on the District Line. The high street hosts a number of buses that will equally accommodate anyone wanting to get into London (237 to connect to the Central Line at Shepherd's Bush; 267, H91 to connect to Piccadilly Line at Hammersmith), or locations further west (391 to Richmond/Kew Gardens).
For those who, like us, have children, the neighbourhood is rammed with green spaces and playgrounds – two of which are within a 10 minute walk from the flat (one almost directly next door, another bigger one around behind the tube lines in Acton). Zoe was extremely accommodating with child-friendly items, including a high chair, bed rail, and baby bath seat. As others have noted, the tube runs behind the building, but it's barely noticeable and for kids provides free entertainment!
We loved this place and were sorry to leave it. When we return to London, we will do what we can to stay here again, if Zoe will have us!
