We stayed in Eleanor's place for 3 lovely months; the house, and Eleanor herself, contributed significantly to having a smooth and unproblematic stay.
Eleanor's place is very good value for money.
We felt right at home from the very beginning. The fact that Eleanor is actually living there contributed to a cosy and hospitable environment. The house was clean and comfortable (for London standards). It also has a great view. All photos shown at the time of writing are accurate.
The location is great for long-term stay (again, for London standards). It is close to a very convenient metro line, as well as to several bus stops that can take you in many places north of Thames quite easily. The neighborhood was very quiet and safe. Nevertheless, if staying in London only for a few days (having limited time for sightseeing), one could consider staying closer to the city center (but this would cost significantly more).
Eleanor is a great host. She prepared the house in a spotless manner before our stay, making sure to provide us with all necessary household items, most of which lasted for our entire stay. This saved us from a lot of fuss. Moreover, Eleanor was always quick to respond to any request, issue, or question we had.
Eleanor left a great "house manual", which included tips for running the house (heating etc), as well as useful information related to London sightseeing, places to eat/drink/shop etc.
In conclusion, Eleanor's place is strongly recommended. We will definitely choose it again if we ever return to London.
