We had a wonderful stay at this apartment. Great location not far from Notting Hill, Kensington and central London. We took Uber everywhere so can't comment on the public transportation. There is a supermarket just across the street that stays open late and has a good selection of grab and go food if you want to eat in. Only the apartment doesn't have a microwave so we used the oven to heat up food.
One thing to note, you will need to walk up four flights of stairs to reach the apartment. So if you have heavy luggage this could be an issue. Although being on the top floor, it's very quiet at night.
All in all it's a very clean, modern and comfortable apartment. And Albert and his wife were great hosts!
