The apartment is very nice and comfortable. It's 'equipped with everything you need and it's very close to the tube station(less than 10 minutes walking).It's 'in zone 4 but Northern line takes you in the center of London in 20 minutes
My husband and I stayed there 12 days and everything was perfect. Just a little thing: if you have a lot of clothes (we hadn't), you have to consider that there isn't a wardrobe but only some shelves.
Oliver is a very kind person
