We spent a pleasant 10 days in Marija's apartment. I would emphasize the peace of the location. Bus stops are a few minutes' walk away, but the accommodation itself is in a side street without traffic or other noise. Several shops (Sainsbury's, TescoExpress, Coop) are nearby with daily opening hours from 7am to 11pm.
During our stay, we realized that taking the bus is cheaper and more interesting (for sightseeing) than taking the subway. There are several lines nearby (77, 87, 137, 345, 452...) that lead directly to the city center within 25-30 minutes, in the end we almost didn't need the subway for sightseeing purposes.
The apartment itself has a living room with a kitchen, two bedrooms and two bathrooms; therefore, it is also pleasant for a longer stay. WiFi is good and stable, supports parallel MS Teams video calls.
On the topic of things to improve :-) the double bed in the bedroom is approximately 190x130 cm in size. If the two of you are slightly longer or larger, it might be tight.
Overall, we are pleased that we chose Maria's accommodation for our stay in London.
