We had a lovely stay in Chiswick. The house is in a lovely quiet (plane noise excepted) area and there are some lovely pubs and restaurants nearby along the river.
The house has everything you could possibly need with the added bonus of a small garden with a trampoline, which my son loved, and also free parking.
Our only “complaint” would be that both double beds were a little on the small side for my 6 foot husband but it wasn’t enough of a problem to spoil our stay.
It’s a fair walk to the nearest tube station especially with a 6 year old and 2 grandparents so maybe not ideal if you are going to be to-ing and fro-ing to the city a lot.
Magdalena’s communication was perfect so all in all we would definitely stay here again if we had the opportunity.
