The flat is conveniently located near Queen's Park with two tube stations and an overground in walking distance and a bus station right around the corner, which makes it easy to get to any corner of the city. Also, there are a couple of grocery stores close by so buying supplies is easy.
The flat itself is spacious and very nicely furnished. The bed was super comfortable. There was everything we needed in the kitchen: oven, microwave, water heater, dishwasher and fridge; as well as in the bathroom: washer (including detergent) and an amazing shower.
Justin and Lou were very nice, greeting us with a bottle of champagne for our anniversary. When one of the lightbulbs didn't work, they supplied a new one the next day.
We had a great experience and are happy we stayed at Justin and Lou's London flat. We would definitely book it again and can only recommend it warm heartedly for a stay in the city.
