The directions to Nana's apartment are excellent - it was very easy to find. Asakusa is a great area to stay with lots to see and do like the Sensoji Temple, rickshaw rides, and amazing street food. The train station is only a short walk along a quiet side street, and from there it is easy to access all the major tourist spots with minimal train changes.
There is a great view of Skytree from the front bedroom (you can walk there quite easily), and you can just see the river through the trees. There is a lovely kids playground outside and Tullys Coffee is a great place for breakfast. The apartment is very spacious with 3 double bedrooms and 2 toilets. It has all the amenities you could need.
The only negative was the road at the back of the apartment was a bit noisy, but this did not detract from our overall experience.
Nana was a wonderful host who responded very quickly to any queries we had, and we would definitely recommend staying at her apartment.
