This apartment was very stylish and a quick 5 minute walk from the station. A quiet neighbourhood with some lovely restaurants (we loved the Italian place right across the street - they were so kind to us!)
Komagome itself is a bit of a distance from Shibuya/Shinjuku or Tokyo station if you are looking to be in the centre of it, but it is on the Yamanote, and it was great for us as we wanted to be close to Nippori for Yanaka and the fabric. And Ikebukuro is great for shopping!
