Lovely house in a charming neighborhood with a lot of space! We loved our stay at Erika’s place, and we highly recommend it. She was there to greet us on arrival, and provided some very thoughtful snacks and drinks for us to start our stay. We are a family of four with two teenagers, and everyone had plenty of space and privacy. The house is really quite large, and we found we didn’t even use two of the five levels. Others have written about the stairs, so we were prepared for them, but note that the kitchen and family room are on the basement level and the bedrooms are on the second and third floors (entry and a sitting room on the first/ground floor), so you will be doing a lot of climbing on a circular staircase. Our teenagers loved the setup of the house, because they were able to have their own floor.
The neighborhood seemed very safe, upscale, and is extremely charming, with many restaurants and a neighborhood pub nearby. The underground stop is only a block or so away, so the location is very convenient for access to London sightseeing. The neighborhood is extremely quiet at night, but street noise does start around 7:00 a.m.
We took the Heathrow Express to Paddington and then the underground two stops to Notting Hill Gate, and found it easy and relatively quick to get to the house from Heathrow (as long as you don’t have too much luggage). The Heathrow Express tickets are considerably cheaper if you buy them in advance online.
