My husband, two young girls ( under 10 years old) and I stayed at Monica's home in November 2015. Monica was a very gracious host and gave us good recommendations for restaurants and local (less touristy) family-friendly sites worth visiting, including Osterley Park and Kew Gardens.
We stayed in the upper floor of her house. The setup was ideal since, with two bedrooms and a bathroom on that level, we were granted tremendous privacy. At the same time, we were still given full access to the rest of the house and made full use of her kitchen and dining room. We enjoyed the highly original and whimsical decor of her home. (I personally liked her Jane Austen-inspired living room by the entrance.
As previous reviewers have already mentioned, her home is conveniently located to major public transit stations. We regularly took the Tube every day and the walking distance for us (with two young children) from her home to the underground station was about 12mins on foot. There is a railway station that is also walking distance. One very convenient aspect is that her home is only a 15min Tube ride away from Heathrow Airport.
The surrounding neighborhood is quite lovely with a culturally diverse feel to it. There are a number of restaurants & pubs within walking distance and many more that are accessible by a 5min bus ride.
All in all, our experience was quite positive and we would definitely recommend her home.
