I enjoyed my stay at Sally's appartment. It is good for single travellers. The location is convenient, because some train stations e.g. also the Yamanote line are in walking distance. Good access to and from the airport.
Sally was a really friendly and attentive host, offering help and advice.
I only wished, there would have been more sunlight in then appartment and you could hear some noise from the street in the morning, but this is quite common for a big city like Tokio unless you stay in a hotel on an upper floor.
Overall, my stay was pleasant and I can recommend this place.
