I booked Octavia's place for my family's Christmas holidays and we thoroughly enjoyed it. It's a very spacious place with plenty of areas for everyone to hang out like the kitchen, living room or garden, as well as spacious bedrooms for privacy. The kitchen is great with everything you might need to cook large meals and the sofa is huge and super comfortable.
I was worried the place might get cold in winter but the heating system works really well and we were super warm at all times.
The steps to access the main door could do with some repairing but there are only a few of them.
Portobello and Notting Hill offer limitless entertainment to suit any taste and you can access central London and the main tourist spots in no time.
I would book Octavia's home again and recommend it without hesitation.
