My husband and two young-adult sons traveled to London for a week over the New Years holiday break. Colette's lovely home was a fantastic base for our travels -- stylish, comfortable and even better looking in person than in the photos.
Check in was very smooth. Colette's housekeeper Pauline kept in constant touch, left the place spotlessly clean, and gave us a great orientation to the space.
Three bedrooms and 2.5 bathrooms were a wonderful bonus for four adults traveling together and the fact that the place is spread out on three floors gave everyone privacy, while the spacious main-floor living room and kitchen was a cozy gathering place (when we walked into the living room-kitchen room, we all said, "Wow!".) The kitchen has a comfortable table, gas stove, dishwasher and lots of small, convenient amenities that made it easy to make breakfasts or snacks at home (we could have easily cooked a full meal there, but didn't because we were fully enjoying the great selection of restaurants in the neighbourhood and throughout the city). There are beautiful windows and French doors throughout -- many overlook a pretty, private courtyard in the back -- making it a light and airy space.
Minor challenges: slightly wonky plumbing (toilets that took a couple of flushes, shower heads in unusual spots) that I suspect are just a normal part of staying in a beautifully refinished vintage home, plus some minor noise from the pub across the road that could only be heard from the front bedroom (but zero noise in the other bedrooms). However, one of my two sons was staying in that bedroom, and he and his brother visited the cozy pub on a couple of nights, so on those nights, it was no problem! :-) The stairs were no problem whatsoever for us (my FitBit was sooo happy), but might be a consideration for travelers with mobility issues.
Last but not least, Colette's location is very convenient to Earl's Court tube station (a 10 minute walk), buses, restaurants, coffee shops and every other amenity you can think of. It's also in an elegant and vibrant neighbourhood.

I would highly recommend Colette's place, especially for a family or larger party who would appreciate space to spread out. Thanks again for your hospitality, Colette and Pauline!
