We really enjoyed our stay in Magali's apartment. The space easily sleeps 5 people and has a nice modern kitchen and comfortable living/dining room where your group can spend time. We were in the Airbnb for 20 days, and it was very convenient to get to central London (a bus just down the street that goes straight to Buckingham Palace, and three train stations within 15 minutes walking). The apartment also had a washer and dryer which were great for our extended stay.
The only downsides were that it could have been cleaned slightly better before we arrived (mostly the kitchen, which had some crumbs and coffee stains on the counter) and the host only provides 1 key for the apartment. The key situation would be very manageable for family that is staying together the whole time, but since we were a group of 5 adults who often split up during the day, it was a bit hard to coordinate.
That being said, I would absolutely stay here again! Thank you Magali for all your help and responsiveness
