Tl;dr: excellent place to stay in West London, good location, outstanding host, definitely recommended.
I can easily recommend this house for short term and long term stay alike.
The house is situated very nicely. It is in Ealing, a diverse and safe neighbourhood. It is close to, but not directly on, the main road, so there's no concern of noise while retaining much of the convenience. Ealing Broadway station is just ten minutes walk away. For short term stay, there're numerous restaurants of different cuisines around the area, you can try a new one everyday and nowhere near repeating by the time you leave. For long term stay, there are several supermarkets within 10 minutes of walk, satisficing every living and cooking needs.
The room is exactly as it shows in the pictures. There's a large wardrobe to the left of the black decorative fireplace. There's enough space even if you arrive with four suitcases. There's a small garden on the ground level, outside of the kitchen. The house is properly warmed throughout the winter, and the cleaner who comes by every week is certainly diligent and everything is clean.
Rosalind and her family live in the house. During my stay, they have always been very friendly, always prepared to lend you a hand should you need one, and always eager to answer your questions about the area, culture, or if you only want to chat. I cannot wish for a better, more accommodating host.
And how can I not mention Bobbi and Rashford! Two lovely, adorable cats whose first birthday I have the honour to celebrate with Rosalind's family! Perhaps they will let you pet them too!
