Do not hesitate to book this AirBnb. It was perfect. It's not near the hustle and bustle of the city, but there is a great pub within walking distance (5 minutes - helpful after pub activities) and a grocery store with a great selection of snacks and alcohol. It's in a somewhat quiet area that is so relaxing (and safe) after our packed days of exploring London. If you walk a little bit further, you'll come across an incredible grocery store with gluten free & vegan options (and amazing eggs!) as well as several restaurants. I highly recommend Cinder Belsize Park - incredible food and atmosphere but tiny, so make reservations.
Our hosts were incredible. They were communicative and kind and left us everything we could need. We had access to laundry, delicious fruit and chocolates, and they even left us a chocolate brioche midway through our trip! We will absolutely be back and can't wait to spend more time at this AirBnb, with our hosts, and in London.
