This is my 4th-time visit to Tokyo,.
So far, this is the best place I stayed, close to Oshiage Skytree station, beautiful environment, and the best part is the balcony facing the Tokyo Skytree. You also can sleep with the view of Tokyo Skytree.
Access to the apartment is also super easy. You can take Narita limited express straight away to Oshiage station and also from Haneda with the same type of train. You do not need to transfer any train from both airports.
I stayed with my 2 kids which are 5 and 7 years old without any problem.
