We had a really good experience with Shinos appartment! It was well located near Tokyo Skytree, metro at +- 10min walk. Asakusa was also close, +- 20min walk, where the Tourism Office could be found and metro. Next to the building there is a Chinese restaurant which is very tastfull and cheap! The owners are super and do their very best to speak English. Supermarket and stores are also close.
The appartment itself is fully equiped with everything you could need. Airco works well but is a little bit noisy (however this never bothered us). It was bigger than we expected and very clean and bright. There's even a place where you can leave luggage and clothes. Wifi works well and fast.
Shino was very helpfull and always answered quickly. She explained very clearly how to go to the appartment and how everything works. When we asked to book an extra night this was no problem and she rent us a big locker to leave our luggage when we arrived.
If we ever return to Tokyo we will surely come back here!
